Tsubaa Gems offers a wide selection of coloured precious stones, including faceted gems, cabochons, and occasionally rough specimens. Catering to jewellers, jewellery students, and lapidaries, the business collaborates with a diverse range of professionals within the trade. Additionally, Tsubaa Gems is passionate about introducing the general public to the world of gemstones and gemology.
Founded by a French sole trader, the business serves jewellers worldwide. With seven years of experience living in London, the founder has a deep appreciation for Great Britain and maintains strong ties to the jewellery industry across the UK.
As a qualified jeweller with a Master of Arts degree (graduated in 2002), the founder understands the technical challenges faced by clients and provides expert guidance in sourcing the ideal gemstones for their designs. Considerations such as market availability, durability, hardness, and care are always taken into account.
All gemstones are personally analysed by an FGA-certified gemologist, and a gemological report can be issued upon request following a purchase.
Tsubaa Gems upholds a commitment to ethical sourcing by working within a short supply chain, partnering with trusted suppliers across various global locations. The business travels to Thailand approximately twice a year to meet suppliers, oversee trading and stone-cutting processes, and personally select goods and special orders.
Most of the stones offered come directly from traders involved in extraction and cutting. Sourcing primarily from Southeast Asia, East Africa, Madagascar, Sri Lanka, India, and Pakistan, the majority of gemstones are cut in Bangkok and other regions of Thailand.
Tsubaa Gems seeks to share a passion for gemstones, a love for jewellery, and a commitment to building meaningful connections within the industry.
