FAQs
What Makes A Lab-Grown Diamond?
There are many names for conventional laboratory grown diamonds: 'man-made', 'created', 'above-ground' or 'synthetic'. They are created by replicating similar high-pressure, high-temperature conditions as mined diamonds. A selected diamond 'seed' experiences these conditions in a lab, crystallising into a rough lab-grown diamond after several weeks. The rough jewel is then cut and polished, resulting in a stone with the same chemical and optical properties as mined diamonds.
Are All Lab-grown Diamonds Created Equally?
No, they are not. Whilst a Skydiamond is technically also a lab-grown diamond, it leads a new wave in man-made diamond creation due to a first-of-its-kind, patent-pending production process, and end-to-end traceability. Skydiamonds are completely clean, created with raw materials exclusively from the sky; C02, Wind, sun and rain. The renewable energy is powered by our sister company Ecotricity, and this informs their carbon-negative status, setting them apart from other lab-grown diamonds in terms of composition, characteristics, and emissions footprint, creating incredibly beautiful stones ordained by nature.
What Is Traceability In This Context?
Skydiamond traceability ensures a 100% transparent journey. All stones over 0.5 carats through the meticulous process of AnchorCert certification. Each diamond over 0.5cts is engraved with ‘SKYDIAMOND’ and a unique code, with an accompanying report and product breakdown. This code becomes an indelible and infinite link between a stone and its origins – We never want to be mistaken for a land-mined diamond.
