About

At Grandjool Ltd., we provide high-quality Ceylon gemstones to a wide range of clients, including retail shops, bespoke jewelers, online retailers, and gemstone dealers. We also cater to collectors, individuals, and anyone seeking the perfect gemstone for their collection or personal use.

​

Ethically Sourced Gemstones

We are committed to sourcing gemstones with ethical principles at the forefront. By working directly with a select group of small-scale artisanal miners and managing our own team of expert cutters in Sri Lanka, we ensure that each gemstone is traceable from its origin, maintaining the highest standards of transparency and quality.

​

Quality You Can Trust

All of our gemstones undergo testing by certified gemmologists. High-value gemstones are accompanied by independent gemological lab reports for your peace of mind. Whether your gemstone comes with a report or not, we stand behind the authenticity and quality of every gemstone we sell.

​

Photography Standards

We believe in presenting our gemstones as accurately as possible. Each gemstone is photographed in a gem light-box under artificial daylight conditions, with additional photos in natural daylight for select stones to give you a true sense of their beauty.
