The 5th Aurora International Gem and Jewelry Competition by GUILD × BELMONT 🏆✨

Step into the serene elegance of a remarkable natural wonder. This exceptional 8.06-carat Jedi Spinel ring captivates with a deeply saturated "Vivid Pink" hue, originating from the rich soils of Tanzania.

Expertly shaped into an oval modified brilliant cut, its unheated purity allows for a striking "Vibrant-brilliance." Enhanced by an "Exceptional Strong Red" fluorescence, the gemstone displays a beautiful, self-luminous depth that shifts gracefully with every angle. Pure, rare, and quietly brilliant.

This remarkable masterpiece is officially competing. Discover its full details on our website.
