Tourmaline 4.39 ct | Cushion | Mint Green | Rubaya, Congo

This exceptional 4.39 ct Mint Green Tourmaline from the Congo stands out for its fresh, energetic color and its elegant elongated cushion shape. Tourmaline is famous for its pleochroism, and this gem displays it beautifully—adding depth, character, and a premium “alive” look in different lighting and viewing angles.

Lively mint color with natural two-tone character (pleochroism)

The gemstone shows a striking, elegant color interplay:

• Bluish green in the center of the stone

• Yellowish green along the edges

This subtle two-tone effect is not a flaw—it’s a natural optical feature of tourmaline and one of the reasons collectors and designers love the gem. It gives the stone a dynamic appearance, with color shifting and depth as the gem moves.

Elongated cushion — modern and refined

The long cushion outline is both timeless and contemporary: soft corners, a graceful silhouette, and a flattering shape for rings and pendants. It offers a sophisticated alternative to standard ovals while keeping a classic, elegant feel.

Precision cutting for full brilliance

This tourmaline was refined and perfected by our in-house cutter, with careful attention to symmetry, proportions, and light performance. The result is a bright, lively gem that returns light beautifully, enhancing both the mint color and the pleochroic two-tone effect.
