0.86ct Green-Blue Tourmaline Gemstone | Carbon & Gold

Displaying a sophisticated blend of deep green and blue, this 0.86 carat tourmaline features an elongated rectangular step cut that emphasizes the gemstone’s rich colour and clean geometry. Broad, linear facets reveal shifting tones of forest green and deep teal as the stone moves through the light.

Its architectural silhouette makes it an excellent centrepiece for a modern custom ring, pendant or horizontally set east-west design. Whether paired with warm yellow gold for contrast or white gold for a cooler, contemporary appearance, this distinctive tourmaline offers a versatile foundation for a truly personal piece of jewellery.

Care & Wear

Tourmaline measures approximately 7–7.5 on the Mohs hardness scale, offering good resistance to everyday scratching while still requiring protection from sharp impacts. It is well suited to pendants and earrings and can be worn in rings when securely set. Clean gently with lukewarm water, mild soap and a soft cloth or brush. Avoid ultrasonic and steam cleaners, harsh chemicals, sudden temperature changes and forceful impacts.
