Crown Gems

Where Sri Lanka's Finest Gemstones await you to Discover..

Crown Gems is a premier destination for a carefully curated selection of one of the Earth’s most exquisite treasures — Gems. Offering a range of high-quality and ethically sourced loose gemstones online, our collection includes sapphires, rubies and a wide range of other gemstones.

Sourced with the utmost care from the depths of Sri Lanka’s gem-rich landscapes, each stone we share tells a story as old as time. Dealing directly at the source, we guarantee the integrity of the supply chain with the most competitive prices catering to both retail and wholesale clients.

All our stones come from the local mines that we own or via our trusted network of local mine owners as we promote responsible luxury. Our team of experts oversees every facet of the supply process, ensuring full traceability to the origins of the gems. With a small-scale mining, cutting, and dealing operation, we take pride in the impact we have made in the local communities in the area, creating many employment and other commercial opportunities.
