Our diamonds are created using cutting-edge technology that replicates natural growing conditions in a lab. This results in diamonds that are chemically and physically identical to the ones sourced from mines
By replicating the mining environment inside a lab we’re able to grow diamonds that are identical to the traditional mined diamonds (but without the shady social and environmental impact). Not even an expert gemologist is able to tell a lab-grown diamond apart from a mined one.
The evaluation of colour is actually based on the absence of colour. A chemically pure and structurally ‘perfect’ diamond has no hue, which gives it a much higher value. Although we tend to think of diamonds as colourless, they range from yellow and brown to grey. There are also ‘fancy coloured’ diamonds but they go off this colour scale as they have a distinct and opulent colour and are valued for their intensity.
Lab grown diamonds enable more transparency in an industry that knows little. Typically mined diamonds come from unethical supply chains in conflict regions, with poor working conditions, low wages and human rights violations. Besides this, between 88,000 and 176,000 pounds of earth must be sifted through to find a single 1-carat diamond, all in the name of ‘rarity’. The environmental impact includes soil erosion, displaced earth, deforestation and ecosystem destruction.
Independent graders like the GIA, HRD, and IGI certify lab-grown diamonds the same way that they do mined diamonds. At Kimai, we send all diamonds above 0.50ct in size to IGI to be graded, though we can provide alternative certificates on request.
