Description
This 11.13 ct Tourmaline from Rubaya, Congo (DRC) combines a fresh leaf green color with an elegant 16 x 12 mm oval cabochon cut. Its generous size, graceful proportions, and softly polished surface give the stone a refined and natural presence, making it especially appealing for bespoke jewelry as well as for collectors who appreciate fine cabochon tourmalines.
Leaf green tourmaline is admired for its lively, natural, and highly wearable appearance. The color feels fresh and vivid while remaining balanced and elegant, offering a green tone that works beautifully in both modern and classic jewelry. In cabochon form, this color often appears especially smooth and even, while the domed polished surface creates a gentle glow rather than the sharper reflections of a faceted gemstone.
The oval cabochon cut gives the stone a timeless and versatile outline. Its softly elongated shape is particularly well suited for statement rings, elegant pendants, and other custom jewelry designs where color and graceful proportions should remain the main focus. The cabochon finish also gives the gemstone a softer and more organic character, making it especially attractive for refined and design-oriented settings.
At 11.13 ct, this tourmaline offers substantial visual presence and clear collector appeal while remaining highly suitable for important jewelry creations. Originating from Rubaya in Congo (DRC), it combines attractive provenance with fresh color, elegant cutting, and strong overall character.
A beautiful oval cabochon tourmaline from Rubaya with fresh leaf green color, smooth luster, and excellent potential for statement jewelry or a refined gemstone collection.
