Understanding Diamonds
Lab-Grown vs. Mined Diamonds
Lab-grown diamonds are categorized as the highest quality, Type IIa, the purest form. They are harder than traditional Type Ia diamonds and only 2% of mined diamonds achieve this perfection.
98% of mined diamonds are Type Ia and contain nitrogen impurities. Most are used for industrial applications and fall short of the brilliance found in Type IIa stones.
Created without adversely affecting the earth or polluting the soil. Zero land disruption, zero conflict. Pure science and craftsmanship.
No guarantee of a conflict-free supply chain. Even Kimberley Process certification has documented gaps and limitations.
Minimum environmental impact: for every 1 carat, only 0.007 sq metres of land disturbed and 70 litres of water used.
For every 1 carat mined, approximately 9 sq metres of soil is disturbed and 500 litres of water consumed, contributing to carbon emissions and air pollution.
Lab-Grown
Type IIa, purest form. Only 2% of mined diamonds achieve this.
Mined
98% are Type Ia with nitrogen impurities, mostly industrial grade.
