Lab Grown Orange Diamonds

Yes, A lab grown orange diamond is not a simulant or a substitute. It is a real diamond, grown in a lab using the same process that happens underground. It comes with a grading certificate and everything. The only thing different is where it came from.

In your hands, no. On a ring, no. Even most jewellers cannot spot the difference without sending it off for specialist testing. The two stones look and behave identically. Origin is the only distinction, and that does not show up when you are wearing it.

If you want something that does not look like every other ring out there, then yes. Orange diamonds are warm, distinctive, and genuinely uncommon. Most people have never even seen one in person. Paired with the right setting it becomes something completely personal rather than just another diamond ring.

Natural orange diamonds are extremely expensive, often well into six figures for anything decent. Lab grown brings that number down quite a bit. The price you pay depends on the carat weight, how vivid the colour is, the clarity, and the cut. Come into our Hatton Garden showroom or drop us a message and we will give you honest pricing based on exactly what you are after.

Rose gold tends to work really well because it brings out the warmth without competing with the stone. Yellow gold does a similar job, particularly with deeper orange tones. White gold or platinum gives a sharper contrast if you prefer a cooler look. Honestly it comes down to what feels right to you and we are happy to show you examples of each.

Fancy colour diamonds are graded on an intensity scale. It runs from Faint at the lighter end through to Fancy Vivid and Fancy Deep at the stronger end. The more saturated and pure the orange, the rarer the stone. A Fancy Vivid orange with no yellow or brown in it is about as rare as it gets in the diamond world.

Every single stone we sell at Flawless comes with a GIA, IGI, or HRD certificate. With fancy colour diamonds this matters more than anything because the colour grade is everything. Your certificate spells out the carat weight, colour grade, clarity, and cut. We would not sell a stone without one and you should not buy one without one either.
