Blue Lab Grown Diamonds

Blue lab grown diamonds capture a beautiful fancy colour without the natural-mined price tag. The colour comes from trace boron introduced during growth, giving cool sky-to-steel blue tones, recreated reliably and certificated to the same standards as colourless stones.

Blue lab grown diamonds are graded for colour intensity rather than the colourless D-to-Z scale, running from Fancy Light through Fancy, Fancy Intense, Fancy Vivid and Fancy Deep. The more even and saturated the colour, the rarer and more valuable the stone. Because the colour is the star, slightly lower clarity grades such as VS and SI are far less noticeable in a blue diamond than in a colourless one, which makes a well-saturated stone a smart value choice. For setting, platinum and white gold keep the focus on the cool colour. Every blue lab grown diamond we supply is independently certificated by IGI or GIA, with the colour grade stated on the report.

Are blue lab grown diamonds real diamonds?

Yes. They are chemically and physically identical to mined diamonds, with the colour created by trace boron introduced during growth, giving cool sky-to-steel blue tones.

What causes the blue colour?

The colour comes from trace boron introduced during growth, giving cool sky-to-steel blue tones. The degree present determines how pale or saturated the stone appears.

Which intensity should I choose?

Fancy and Fancy Intense offer the best balance of strong colour and value, while Fancy Vivid is the most saturated and most sought-after.

Are blue lab grown diamonds cheaper than mined?

Considerably. A lab grown fancy blue typically costs a fraction of an equivalent natural fancy stone of the same size and intensity.
