Natural Gems for Every Need

Koya Gems & Jewelry LLC FZ operates from the heart of Dubai’s free-zone network, channeling the emirate’s world-class logistics to jewellery manufacturers and designers across the Gulf, Europe, the United States, Russia and China.

Our founder brings more than seven years of hands-on gemstone expertise, guided by a mentoring team whose collective career spans over twenty-seven years at the highest levels of the trade.

Together, we share a single ambition—making it effortless for jewellers to secure impeccably cut, 100 percent natural stones exactly when production schedules demand them.

Our mission takes full advantage of Dubai’s status as a gateway city. By maintaining deep inventories of calibrated emeralds, rubies and blue sapphires for mass production, alongside single-piece centre stones and astrologically significant gems.

Every stone we sell is 100 % natural—no hidden treatments—and we ship quickly from Dubai to customers across the Gulf, Europe, the USA, Russia, China and across the globe. Whether you are filling a large production order or designing a single bespoke piece, tell us what you need and we’ll put the right gems on their way to you.

At Koya Gems & Jewelry we keep buying gemstones straightforward and reliable for both jewellery businesses and individual shoppers.

Popular shapes—ovals, rounds, squares, marquise, pears, octagons and baguettes from 1 mm up to about 6 mm—arrive colour-matched and clarity-graded, so your production line stays consistent without extra sorting.

When you need just one special stone, our loose-gem section lets you pick the exact emerald, ruby, blue sapphire or yellow sapphire you want, from roughly 0.30 ct to 5 ct and larger. Choose the shape, size and shade that suits your design; we can supply an independent lab report if you’d like extra assurance.
