Spinel 1.08 ct | Pentagon | Greyish Blue | Ratnapura, Sri Lanka

This 1.08 ct Spinel from Ratnapura, Sri Lanka, combines an uncommon pentagon cut with a sophisticated greyish blue color. Sri Lanka is one of the world’s most respected sources for fine spinel, and Ratnapura is especially known for producing gemstones with attractive natural colors and individual character. This stone stands out through its unusual shape, refined tone, and modern overall appearance.

The color shows an elegant greyish blue character with a calm and understated look. Rather than relying on strong saturation alone, this spinel impresses through its subtle blend of cool blue and soft grey, giving it a contemporary and highly individual aesthetic. Such tones are especially appealing for buyers who appreciate unusual gemstones with a more refined and understated presence.

Its pentagon cut gives the stone a striking and architectural appearance. Far less common than traditional shapes, it offers a modern and distinctive look that works especially well in custom jewelry. The geometric outline makes this spinel particularly suitable for contemporary rings, creative pendants, and one-of-a-kind designer pieces where the shape itself becomes part of the design statement.

At 1.08 ct, the stone has a practical and versatile size for fine jewelry. It is large enough to show its color and unusual cut clearly, while remaining comfortable for everyday wear. Set in white gold or platinum, the greyish blue tone appears crisp and modern; in yellow or rose gold, it takes on a warmer and more individual contrast.

A refined greyish blue Spinel from Ratnapura with an uncommon pentagon cut, elegant natural color, and distinctive character—well suited for bespoke jewelry and carefully selected gemstone collections.
