Product Introduction
Spinel is highly valued in the fine colored-gemstone market for its bright brilliance, excellent luster, and wide range of colors. Among these, varieties with a distinct color-change effect are especially fascinating because they can display dramatically different colors under different light sources.
This exceptional 7.87 ct color-change cobalt spinel appears clean to the eye and features a full cushion-shaped outline with a broad table that highlights the gemstone’s transparency and color. Under different lighting conditions, it can shift from vivid blue to pink and purplish-pink tones, creating a highly distinctive dual-color appearance.
The gemstone is accompanied by a GUILD Platinum Certificate, combining unusual color behavior, substantial carat weight, and strong collector appeal. It is suitable either as the center stone of bespoke fine jewelry or as a standalone loose-gemstone collectible.
