What is a lab grown diamond?
A lab grown diamond, also called a Laboratory grown or manufactured diamond is a real diamond created in a controlled laboratory setting using advanced technology that replicates natural diamond formation. In the UK, Lab grown diamonds are becoming increasingly popular because it offers the same purity and quality as mined diamonds but at a more affordable price with a sustainable and ethical origin.
Are lab grown diamonds real?
Yes, lab grown diamonds including those available in the UK are completely real. They have the same chemical composition, crystal structure, and optical properties as natural diamonds, making them indistinguishable even under a jeweller’s loupe.
The key difference lies in their origin—while natural diamonds form deep within the earth over billions of years, lab-grown diamonds are created in high-tech laboratories using advanced processes like High Pressure High Temperature (HPHT) or Chemical Vapour Deposition(CVD).
These methods replicate the natural diamond-growing conditions, resulting in a gemstone that is just as brilliant, durable, and valuable—only more sustainable and ethical.

How Laboratory Grown Diamonds are made?
Lab grown or man made diamonds are created in high-tech laboratories using two advanced methods: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD).
HPHT Method: This process mimics the earth’s natural diamond formation by exposing a tiny diamond seed to extreme heat (over 1,500°C) and high pressure (about 1.5 million PSI), causing carbon atoms to crystallise and grow into a diamond.
CVD Method: In this technique, a diamond seed is placed in a chamber filled with carbon-rich gas and exposed to high temperatures. The gas breaks down, and carbon atoms bond layer by layer, forming a pure diamond.
Both these processes are used by the UK jewellers who specialise in Lab grown diamonds.

Diamond Color
When in the market for a diamond, it’s preferable to select a stone with the least amount of color possible. The color of a diamond is graded on a scale ranging from D-Z and is divided into five main categories: colorless, near colorless, faint, very light, and light. Diamonds come in various colors of the spectrum, with yellow being the predominant color due to the trace element nitrogen.
When comparing the color of two diamonds, the diamonds need to be at least two grades apart for any difference to be noticeable. As shown in the accompanying images, it’s nearly impossible to detect any color when diamonds are in the face-up position. While some color may be observed from the side profile, the beauty of a diamond is best appreciated from the face-up position and not the side.
Colorless Diamonds (D-F):
The colorless range of diamonds is the most rare and valuable on the color scale. D/E colored stones display practically no color, while F-colored diamonds show a nearly undetectable amount of color when viewed face down by a gemologist.
Near Colorless Diamonds (G-J):
Diamonds within the near colorless range appear colorless when viewed face up, but show a slight amount of color when viewed face down against a perfectly white background. This trace amount of color will be unnoticeable to an untrained eye once the diamond has been mounted. Near colorless diamonds offer great value for their price.
Faint Color Diamonds (K):
Diamonds in the faint color category may display a slight hint of color when viewed in the face-up position. Nevertheless, they are still a wonderful option for those who are not sensitive to color. Some even appreciate the color scheme displayed by these diamonds.
K Color
Although yellow is the most common color found in a diamond, it’s not unusual for a diamond to have a brown hue. This is thought to result from internal graining, which occurs due to structural irregularities, often in combination with impurities like nitrogen.
