Natural round tanzanite for jewelry

If you're looking for a unique gemstone with enchanting brilliance and an exotic origin, natural tanzanite is a must-have for your collection or design catalog. In our store specializing in the sale of loose gemstones, we offer round-cut loose tanzanites in vivid blue, ideal for fine jewelry projects or for incorporating into distinctive custom pieces.

The available sizes—2 mm, 3 mm, 4 mm, 5 mm, and 6 mm—suit both delicate work and larger-scale designs, offering versatility for goldsmiths, designers, and collectors. The weight of each stone varies depending on the size selected, but we always guarantee harmonious proportions and quality of cut.

Blue tanzanite was officially added as the birthstone for December, becoming a contemporary alternative to zircon or turquoise. Its deep, luminous color makes it perfect for celebrating births, anniversaries, or special moments that occur in the last month of the year.

Furthermore, thanks to its rarity—found only in a small area at the foot of Kilimanjaro, in Tanzania—each tanzanite used for jewelry design represents a choice of increasing value, not only aesthetically, but also emotionally and symbolically.

With a hardness of 6 to 6.5 on the Mohs scale, round tanzanite requires proper setting and a certain delicacy in its use, making it most appreciated in cocktail rings, earrings, pendants, and pieces that are not exposed to constant impacts.

Its most striking characteristic is pleochroism: the ability to display different hues (blue, purple, or even pink) depending on the angle of the light. This quality makes each tanzanite jewelry specimen shine uniquely, adding depth and intensity to any creation.

From our jewelry gemstone platform, we offer carefully selected tanzanites ready to be set. Whether you're making a custom piece of jewelry or developing a complete collection, our loose natural tanzanites are an excellent choice to add exclusivity to your work.

If you need a specific size outside of the standard catalog, or are looking for a tanzanite to make jewelry with unusual characteristics, we offer a personalized search service thanks to our network of suppliers in Africa, Asia, and Europe.

We also offer free shipping to any country in the world and offer special rates for volume purchases. If you are a jeweler, distributor, or work in the fine watchmaking sector, you can contact us for wholesale discounts and personalized attention.

We are dedicated exclusively to the sale of loose gemstones, offering a professional and transparent experience. All our gems can be accompanied by a gemological report upon request. Furthermore, we guarantee that each natural blue tanzanite has been expertly verified and is of clear and ethical origin.
