Description

This 1.53 ct Tourmaline from Rubaya, Congo (DRC) combines an elegant antique oval cut with an attractive bluish green color. Its refined shape, lively appearance, and balanced size make it an appealing gemstone for fine jewelry as well as for collectors who appreciate natural tourmalines with character and individuality.

Bluish green tourmaline is especially admired for its sophisticated mix of cool blue and fresh green tones. This combination gives the stone a vivid yet elegant look that feels both modern and timeless. Depending on the lighting, the gem may show a slightly cooler or greener impression, adding depth and visual interest to its overall appearance.

The antique oval cut gives the stone a graceful outline and a more distinctive personality than a standard oval. Its elongated proportions create an elegant presence, while the cut style adds a subtle vintage touch that works beautifully in both classic and contemporary jewelry. This makes the gemstone particularly well suited for rings, pendants, and bespoke jewelry designs where a refined center stone is desired.

At 1.53 ct, this tourmaline offers an excellent balance between presence and wearability. Originating from Rubaya in Congo (DRC), it combines attractive provenance with elegant cutting and a beautiful bluish green color.

A refined antique oval tourmaline from Rubaya with lively bluish green color, elegant proportions, and excellent potential for fine jewelry or a carefully selected gemstone collection.
