About the Business

Based in London and Colombo, Roughcut Ceylon specialises exclusively in natural Ceylon sapphires, supplying exceptional loose sapphires for engagement rings, wedding rings, and bespoke fine jewellery. With a particular focus on rare unheated stones, we carefully source ethically sourced sapphires celebrated for their natural beauty, brilliance, and individuality.

As a second-generation family-run business with over 50 years of expertise, we combine trusted gemstone knowledge with direct sourcing from Sri Lanka, the historic source of some of the world’s finest sapphires. By working closely with trusted local miners, cutters, and suppliers, we maintain a transparent and responsible sourcing process that respects both craftsmanship and origin. From classic royal blue and cornflower sapphires to rare padparadscha and unique bi-coloured stones, we help couples discover a gemstone that feels deeply personal and entirely one of a kind.

Roughcut Ceylon is headed by Dr Gamini Zoysa, a world-renowned gemmologist, former President and current Executive Committee Member of the Gemmologists Association of Sri Lanka (GASL), as well as former Sri Lankan President and Ambassador to the International Colored Gemstone Association (ICA).

Every sapphire is individually selected for its quality, character, and suitability for heirloom jewellery, offering an elegant and meaningful alternative to traditional diamonds for modern wedding and engagement rings.
