Diamond Buying Mistakes

Diamond Buying Mistakes

Buying diamonds isn’t something that you want to do lightly. You need to consider your purchase carefully before you decide which diamond is right, whether it’s attached to a piece of jewellery or you’re buying a diamond on its own. If you’re not careful, there are various mistakes that you can end up making when buying diamonds. Fortunately, it’s easy to avoid some of the biggest mistakes by being aware of them and knowing what you should be doing instead. If you’re about to buy a diamond or diamond jewellery, remember the following mistakes and how you can avoid making them.

Not Taking Your Time

It’s always important to spend time considering a large purchase. It’s even more important when you’re choosing something that should last for many years. You wouldn’t buy a car or a house without thinking it over, so it’s best to treat the purchase of a diamond the same. If you rush into the purchase, you could discover that you’ve made a big mistake not long after buying it. Doing some of your own research is a good start, but the best thing to do is often to get the opinion of a professional if you want to make sure you have the help of someone who knows what they’re talking about.

Ignoring the 4Cs

Knowing about “the 4Cs” is essential when you’re buying a diamond. These are the four characteristics that determine the quality and the beauty of a diamond. They are the cut, clarity, carat and colour. While all of these are important, some say that the cut of the diamond is what matters most. Even if the other elements are not as optimal, a good cut can make a diamond sparkle and shine. It can make the colour and clarity look better and even enhance a diamond with a low carat weight.

Thinking You’ve Found a Bargain

It’s simply a fact that if you want to buy a diamond, you need to be willing to spend a bit of money. Of course, there are different options to suit different budgets. Compromising on carat size or clarity can be a way to save money, for example. However, you should be aware that you’re unlikely to find similar diamonds for drastically different prices. Diamonds have a relatively fixed wholesale price, meaning you won’t find much difference in price between two diamonds that are the same carat, colour, clarity and cut. If you find one that seems very cheap, it’s likely too good to be true.

Only Thinking About the Diamond

The diamond is, of course, an essential thing to consider when buying a piece of jewellery. However, whether you are buying an engagement ring or treating yourself to a diamond, it’s not the only thing you need to think about. You should also think about where the diamond will be set. You need to think about how a diamond will sit in the ring or other setting, considering things like size and colour to make the right choice.

Take your time when choosing a diamond to get the best diamond available. Avoid these mistakes and you will be able to find the right diamond.

An in-depth Guide to Buying an Emerald Engagement Ring

An in-depth Guide to Buying an Emerald Engagement Ring

By Flawless Fine Jewellery

This buyers guide is designed to help you buy the perfect emerald engagement ring, with 100% certainty that you have bought the right stone!

A brief history of Emeralds

Since antiquity, emeralds have been coveted for their intense, vibrant, green colour. Cleopatra famously had her own mines dedicated purely to the excavation of the gemstone. The mines (sadly no longer in use) were operated by hundreds of men whose existence was solely focused on procuring her green gems.

Even today, emeralds are still held in the same high regard. Recent emerald connoisseurs include the likes of Elizabeth Taylor and John Rockefeller jr; both of whom’s emerald jewellery has broken world records when sold at auction with the latter and formers jewellery selling for $5,511,500 and $24,799,000, respectively.

In stark contrast to the past when emeralds were predominantly mined in Egypt, you’ll find that over 60% of the world’s emeralds come from Colombia with the majority of these stones being split among 3 massive mines: Muzo, Coscuez and Chivor located within the Andes mountain range which runs northeast-southwest through the country.

Recently emeralds are having a resurgence in popularity, with lots of american jewellers keeping a rich stock of columbian emeralds due to this fact. Alongside Colombian emeralds are Zambian emeralds, these are popular because they also sport the rich green colour and, in contrast to Colombian emeralds it is very easy to find two stones of matching quality.

When shopping for emeralds it is important to remember that location can drastically affect the price. For example, when a stone comes from Colombia in that desirable, green colour and quality, the price of that stone can be exponential compared to an equally beautiful stone from Zambia or Afghanistan; which have also been known to produce high quality emeralds (though afghan stones are less common these days).

Emerald Quality

This section is designed to educate you on what your criteria should be when choosing the perfect emerald.

Taking all of the previous information into account, when purchasing an emerald your priorities should be: colour, clarity, saturation, origin, treatment and certification, respectively.


Firstly colour plays a huge part with emeralds. All emeralds are dichroic (this means that the stone has 2 colours the primary green and a secondary blue or yellow, these secondary colours are also called hues), blue is generally considered to be the better colour because it is a darker tone which benefits the saturation (see Saturation section for more information) so when choosing to buy your emerald the most desirable colours range from a lovely bluish green to a pure vivid green with a very rich colour while featuring a medium to dark tone.

in emeralds clarity is a key factor in terms of quality, the most coveted emeralds have a good amount of transparency. Clarity refers to the amount of inclusions and blemishes contained within a stone, all emeralds contain inclusions this is unavoidable due to how they form within the earth and finding an emerald with no inclusions is the first sign of a synthetic stone (all natural emeralds have inclusions, this is how they are distinguished from their synthetic counterparts).

The left emerald features beautiful colour and the expected amount of inclusions from a high quality stone.

The right emerald while having beautiful colour is however heavily included which greatly decreases the stones quality and thus the stones price.


While transparency is good sometimes you can find an emerald containing a window (which is when the colour in the centre of the stone lacks depth compared to the rest of the stone)which can make the stone less desirable and is a sign that the stone has been cut poorly making it too shallow.
On the left we have an example of a perfect quality emerald. On the right we have a very clear emerald containing a central window.

Saturation and Tone

In emeralds saturation of colour plays a big part in their quality (and worth) as a lighter colour stone which has a lower degree of saturation is normally less desirable than it’s more saturated counterpart, this owes to the fact that emeralds are more coveted and thus more expensive when they are that darker lime colour. Tone is the type of colour the emerald holds e.g a lighter colour or a darker colour. Tone helps to determine the saturation of the emerald, due to the secondary colour. For example a lighter tone means less saturation (this is more common in stones with a yellow secondary colour hence a blue secondary colour being preferred) and a darker tone means more saturation (more common in stones with a blue secondary colour). However your choice should be a stone that has a good mix of tone and saturation. Go for a stone that has a medium bluish tone while having that vivid lime green. (for example the stone seen below)


Your stones origin is important due to its geographical birthplace have a rather significant effect on the price of your stone, as well as stones from different regions having different elements present during their formation, which in turn lend themselves to changing the properties of the stones.


Colombia is the most reputable source for emeralds, and its 3 mines have been running since the early 1500s when the Spanish came to South America, and began exporting the stones back to Europe and the Far East. Colombian emeralds are valued for their rich green saturation and medium bluish tone which combine together to create that vivid green colour that is so highly coveted in emeralds. Colombian emeralds are also known to contain a lot more inclusions that other locations due to their forming in sedimentary rock. They often contain a large amount of thin string-like inclusions called jardin (garden in french).

Emeralds from Colombia owe their higher price to their more prestigious reputation as well as the difficulty that comes with cutting the rough stones. This difficulty comes from how the colour of the emerald is distributed inside the rough, and the constant possibility that the cutter can take away all the colour with one wrong cut, due to the colouring agents being mainly situated around the stones exterior. This risk means that cutting colombian emeralds requires a higher degree of expertise thus incurring more costs and adding to the overalls stones price at sale.
this stone is a premium example of a Colombian emerald in terms of quality.(this stone also features a Jardin).


So we have already established that Colombia is the “gold standard” for high quality emeralds, but up there with Colombian emeralds is Zambia, and while the history behind Zambian emeralds is young in comparison to Colombia, Zambia is slowly becoming a reputable source of beautiful emeralds!

Mining for Zambian emeralds was first initiated in 1976 at the Kagem mine. However the mine did not start producing high quality emeralds consistently until 1984. In 2005 Gemfields (the leading excavator of Zambian emeralds today) began mining in and around Kagem. Then in 2007 Gemfields created a partnership with the Zambian government establishing a 75/25 split ownership of the Kagem mine. I think it is fair to say that Gemfields are responsible for making Zambia the lead provider of emeralds worldwide (20% of emeralds in the world come from Kagem) and in 2009 excavated a shocking 27.6 million carats of rough emeralds!

Zambian emeralds while held in a lower regard to Colombian(due to colombia having a longer history and more ingrained popularity in the gemstone market) are still very beautiful stones holding a very deep vivid green colour, and contain less inclusions that Colombian stones. Zambian emeralds are also harder than colombian (zambian emeralds can range from 7.5 to 8 on the mohs scale while colombian stones stay at 7), which enables them to be cut with less fear of ruining the stone.

In terms of quality Zambian emeralds are known to hold a slightly darker bluish tone than their Colombian counterparts, due to the presence of iron and vanadium during formation. This darker tone means that lower quality Zambian emeralds are quite common due to said tone negatively impacting the saturation of the stones. (see saturation and tone chart featured above)

This zambian emerald is a prime example of the darker blue tone this is common in zambian stones.


As emeralds are very soft stones often they are found to contain striations or fractures within the stone. To combat this most emeralds are treated with oil which then fills these cracks improving the emeralds clarity. All emeralds are graded on their level of treatment and all emeralds are placed in type 3 of GIA’S categories for coloured gemstones. Because of this oil or resins are used to increase their standing on the type scale.

When choosing an emerald it is normally best to choose a stone with minimal treatment, because a traditional treatment like cedarwood oil will dry out over time, making the inclusions more prevalent. So if a stone has been heavily oiled, when it dries out it will reveal a lot of inclusions ruining the stone.

Type 1 gemstones: These are typically inclusion free, or almost inclusion free.
Type 2 gemstones: These gemstones are usually included.

Type 3 gemstones: These are almost always included.

Natural AAA: This is the highest quality. It represents are the top 10% of gemstones. Natural AAA emeralds are rich green, moderately to slightly included, and they exhibit very high brilliance.

Natural AA: This is the second-best category for gemstones. Natural AA gemstones account for 20-30% of all gemstones. Emeralds in this category are medium green and may include moderate inclusions.

Natural A: This category accounts for 50 to 75% of all gemstones. Natural A emeralds are dark green, heavily included, and opaque. They are still good, but they are considered to be of a lower quality compared to the two categories above.

Apart from Natural AAA, AA, and A, there’s also a category called Heirloom/Rare Emerald. This is the highest quality, even better than AAA. They are extremely rare and expensive.- taken from

Gemological reports usually indicate the level of clarity enhancement for emerald, ranging from None to Insignificant, Minor, Moderate and Significant.- taken from

Many different oils and resins are used when treating emeralds, but the most common is cedarwood oil which is used for due to it’s colourless nature and refracting light at a similar scale to emeralds. In the 1980’s Brazil began using a synthetic resin called opticon which was quickly acquired by colombia, and became popular because of its better stability (does not dry out like oil meaning one time usage), and have a refractive index which was almost identical to emerald (a refractive index is a dimensionless number that describes how fast light travels through the material). the use of this resin sent shockwaves the jewellery market because many emeralds were being distributed with this treatment but were being labelled as no treatment used, which caused buyers to become nervous about buying stones from Colombia.


The last detail to cover about emeralds is certification. Unlike with diamonds GIA is not the best choice for coloured stone certificates, instead the 2 most reputable and trusted certifiers of coloured stones are Gubelin and SSEF. Both of these laboratories take the certification of stones very seriously and thoroughly: inspecting, analysing and grading stones with the utmost care and precision. While both certifiers will inform you to what degree your stone has been treated, neither can inform you what treatment agent has been used as “They refuse to specify the exact type of treatment agent not because it is impossible to identify it, but due to the fact that these laboratories will only state in writing what they can say with 100% accuracy. SSEF is the only Swiss lab that gives any indication of the treatment type, classifying it as either ‘traditional’ or ‘modern’,” ( quote by george smith co-founder of International Emerald Exchange). These classifications of modern and traditional are used to reference whether the stone has been treated with a natural oil (e.g cedarwood oil) or a synthetic resin (like opticon).

To conclude this article i have decided to round out all the key points of each section to make it easier for you to remember what your criteria should be.  Since saturation and tone affect colour they will all be grouped as one area. This is the same for clarity and treatment.

  • Colour: the perfect colour is around the strong lime green area, without any windows within the stone and not having too dark of a secondary tone (preferably blue). The picture below is an example of a stone with these criteria.
  • Clarity: all emeralds have inclusions so you should not go out looking for a perfectly clear stone, instead you should look for a stone with less noticeable inclusions and minimal treatment so that you know the stone will hold its beauty.
  • Origin: the emeralds origin is important, because Colombian emeralds contain different minerals to Zambian emeralds, which means they have different attributes. If you want a lighter green emerald with a light blue tone, Colombia would be the better choice but the price would be higher. Zambian emeralds are the better choice for darker more saturated colour, due to the presence of iron making them have a slightly grey tone and the price will be lower.
  • Certification: when buying a high quality emerald, it is always important to make sure the stone is certified, especially if the seller said that the stone is from Colombia as the certificate will be able to verify its origin, as well as if the stone has been treated and to what extent. Certifications are important because they allow you to be 100% certain you are receiving what you initially paid for.

Best Places To Propose

Best Places To Propose

A proposal should be a carefully thought out thing that you’ve spent lots of time mulling over. You need to consider what will make your proposal as special as it can be. Obviously, choosing the right ring is the number one thing to do. Then, it’s all about the setting. An excellent and romantic setting can make your proposal ten times better.

So, with that in mind, here are the best places to propose in the world:


Nothing says romantic quite like a proposal in Paris. People come from all over the world to get down on one knee beneath the Eifell Tower and pop the question to their loved one. It makes for the most fantastic setting, and it’s hard to recreate the atmosphere anywhere else. Partis is the city of love, and you’ll undoubtedly feel all the love with a proposal here.


Like Paris, Venice is an iconic place for lovebirds. We recommend planning your entire day around this proposal and doing it in the evening. There are loads of romantic canals throughout the city, and you will see some stunning settings. If possible, try and propose on a Gondola during a ride around the canals. It can be tricky, but it’s worth trying. If not, go for a lovely ride, have a romantic dinner looking across the Grand Canal, then pop the question here. Try having a word with the staff at the restaurant as they might set something up and play lovely romantic music for you.


One of the most luxurious and gorgeous Greek Islands, Santorini is the perfect place to propose. The scenery throughout the island is second-to-none, but there’s one thing that makes it one of the best places to propose; the sunsets. They are incredibly here, and you should definitely propose out on one of the sandy Santorini beaches as the sun sets behind you. It makes for phenomenal photo opportunities, and you’ll feel overwhelmed with romance.


While it might not be as globally recognised as a romantic city, London holds loads of stunning spots for proposals. Amongst the many ideas, we’ve picked out Tower Bridge as the best one. Firstly, it’s an iconic London landmark that provides you with excellent views of the city and across the Thames. Secondly, you can privately book the walkway at the top, specifically for your proposal. In essence, you have the bridge to yourself, and you can decorate it however you want. This lets you conjure up the most romantic and intimate setting with no-one else around. There are other places in London to propose – The Shard and The London Eye are both romantic ideas – but we think this one is the best.

Never rush into a proposal, it should be carefully thought out. The more thought and attention you put into it, the better it will be, and your other half will be even more appreciative. Of course, don’t forget to buy the best possible engagement ring. At Flawless Fine Jewellery, we let you design the perfect ring for your betrothed. Think about all the hints they’ve dropped over the years, then create a ring that’s made especially for them. Now, you can propose with the perfect ring in the perfect setting!

Choosing diamonds or gemstones

Diamonds are a traditional choice for engagement rings but there are plenty of other options available. Exquisite blue sapphires, rich green emeralds and deep red rubies are also popular choices for engagement rings and it’s easy to see why. With the option to customise your ring entirely, you may even choose to have a centre gemstone surrounded by smaller diamonds.

If a particular stone has meaning for your partner or even if you want to incorporate their favourite colour into your ring design, using a gemstone can be a fantastic option. With plenty to choose from, you’re sure to find the perfect colour, shade and hue when designing your custom engagement ring.

Selecting a setting

If you don’t know too much about jewellery, you may not be aware that diamonds and gemstones can be set into engagement rings in different ways. The classic Halo setting uses a centre diamond and a surround of smaller diamonds, for example, while a claw setting uses four or six prongs to hold a centre stone in place.

Typically, the type and size of stone you choose will determine which settings are most effective. However, designing a custom engagement ring gives you plenty of scope to incorporate your preferred settings.

Finding the right cut

With endless cuts to choose from, you can select the perfect option for your partner. A brilliant cut diamond offers unrivalled sparkles, whilst a step cut is perfect if you prepare a clean, sleek design. If you want to design something unique and modern, hexagonal and triangular diamonds will ensure your custom engagement ring stands out. Whether you opt for a princess cut, oval, square or heart-shaped stone, the cut of the diamond or gemstone will be one of the most important features of your bespoke engagement ring.

Picking the right band

Firstly, you’ll need to decide what type of metal you want to create your custom engagement ring from. White gold and platinum have a silver hue, while yellow gold and rose gold have a warmer, pink tone.

Once you’ve chosen the right metal for your engagement ring, it’s time to consider the band itself. Whilst some people prefer the simplicity of a metal band, others choose to add some extra sparkle. If you want to add diamonds or gemstones to the band itself, you can opt for a range of settings, such as scallop, bezel or channel.

With so many options to consider, creating the perfect custom engagement ring can seem overwhelming at first. Fortunately, help is at hand. To find out more about designing your bespoke engagement ring, contact Flawless Fine Jewellery now on 020 7404 8306.
