Description
This 38.73 ct Tourmaline from Minas Gerais, Brazil is an exceptional gemstone with impressive size, a refined cushion cabochon cut, and an attractive bluish green color. Measuring 19 x 19 mm, it offers outstanding presence and a strong visual identity, making it especially suitable for high-impact bespoke jewelry and for collectors who appreciate rare and substantial tourmalines.
Bluish green tourmaline is admired for its elegant balance between cool blue undertones and fresh green color. This combination gives the stone a lively yet sophisticated appearance, with a tone that feels both distinctive and highly wearable. In cabochon form, the color appears especially rich and even, while the polished domed surface creates a smooth, luminous glow rather than the sharper brilliance of a faceted gem.
The cushion cabochon cut gives the stone a bold yet elegant outline. Its softly rounded square shape combines excellent presence with timeless appeal, making it particularly well suited for statement rings, substantial pendants, and other custom jewelry designs where the gemstone is meant to remain the clear centerpiece. The generous 19 x 19 mm size further enhances its suitability for important one-of-a-kind creations.
At 38.73 ct, this tourmaline belongs to a category of gemstones valued not only for jewelry potential but also for their collector appeal. Originating from Minas Gerais, Brazil, one of the world’s most respected gemstone regions, it combines notable provenance with impressive scale, refined cutting, and attractive natural color.
