Collection: Lab-Grown Coloured Gemstones

Explore specialty-cut lab-grown sapphires and alexandrite for custom jewellery, matched pairs and repeat-production designs. The collection includes Dutch marquise and elongated hexagon cuts, pear, Sakura-style and other brilliant, step and old-mine-style designs. “Czochralski-pulled” is used only where the growth method has been confirmed for that product.

Check each product page for material, target dimensions, colour description, faceting style, report status and exact-stone or repeat-production terms. Repeat-production stones can vary within the stated tolerances, and colour-change appearance can vary with lighting and display conditions. Need another size, colour, pair or quantity?
