Description

This 1.83 ct Tourmaline from Rubaya, Congo (DRC) stands out through its attractive jungle green color and its distinctive roundish shape. With its vivid natural character and balanced size, it is a gemstone that offers both individuality and versatility, making it well suited for fine jewelry as well as for collectors who appreciate expressive colored stones.

Jungle green tourmaline is valued for its rich, saturated appearance and lively natural energy. The color suggests depth and freshness at the same time, giving the stone a bold yet elegant look. Compared with lighter greens, this stronger tone creates more presence and makes the gemstone especially appealing in jewelry where color should remain the main focus.

The roundish shape gives the stone a softer and more individual outline than a standard calibrated cut. This can be especially attractive in bespoke jewelry, where unique proportions and natural character are part of the finished design. The gem is particularly suitable for rings, pendants, or other custom creations that benefit from a vivid green center stone with personality.

At 1.83 ct, this tourmaline offers a very good balance between visual presence and everyday wearability. Originating from Rubaya in Congo (DRC), it combines desirable provenance with strong color and a distinctive overall appearance.

A vivid jungle green tourmaline from Rubaya with natural charm, attractive presence, and excellent potential for custom jewelry or a carefully selected gemstone collection.
