Description
This elegant companion pair of Mint Green Tourmalines from the Congo is made for modern, design-driven jewelry. With a combined weight of 10.20 carats, the two stones are matched in color and cutting style, yet differ in size—creating a sophisticated, intentional contrast that looks especially striking in contemporary settings.
Distinct pleochroism: natural two-tone mint character
Tourmaline is famous for pleochroism, and this pair shows it beautifully. Each stone displays:
-
a bluish-green core that feels cool and refined
-
yellowish-green edges that add brightness and lively energy
This natural two-tone effect gives the gems depth and movement, changing subtly with angle and light.
Matching look, different size — perfect for modern design
Because the cutting and color character are consistent, the stones feel like a true pair—just with a deliberate size difference. That makes them ideal for:
-
toi et moi rings (two-stone rings), where contrast is part of the style
-
a pendant + matching ring, using one stone in each piece
-
coordinated sets with a modern, asymmetrical concept
Cut to perform
Both stones are cut to maximize brilliance and a clean face-up look, enhancing the fresh mint color and the pleochroic two-tone appearance. The result is a pair that looks lively, bright, and premium in jewelry.
A modern mint-tourmaline duo from the Congo—matched in character, intentionally uneven in size, and perfect for contemporary two-stone designs.
