Blue Gemstones
Blue is the most collected color in gemstones, and no two species hold it the same way. Our blue gemstones include natural sapphire from Sri Lanka, Montana’s Yogo Gulch and Australia, vivid tanzanite, brilliant Cambodian blue zircon and aquamarine from a few carats to over 39.
Every loose gemstone here is chosen one at a time and documented with its own Digital Gem Passport; rated stones carry an Otzera 50 score judged against their own species. New to blue? Start with our sapphire guide.
