Monumental 9.32ct Natural Mahenge Spinel –Hot Pinkish-Red “Sugarloaf” Cabochon
Behold a rare giant of the gemstone world: a 9.32-carat Natural Mahenge Spinel masterfully carved into a majestic Sugarloaf cut. This architectural masterpiece combines the high-profile volume of a pyramid with the smooth, polished curves of a cabochon, creating a “mountain” of intense, neon-pink color that is impossible to ignore.
Sourced from the legendary Mahenge mines in Tanzania, this stone boasts a vivid hot pink hue with a subtle, electric glow. The sugarloaf cut is specifically chosen for stones of this immense size and character, as it highlights the gem’s rich saturation and “velvety” internal texture while offering a bold, three-dimensional presence that towers above standard cuts.

The Majesty of the Sugarloaf
The sugarloaf cut is one of the most prestigious and difficult cuts to execute properly. It requires a significant amount of high-quality rough material to achieve such a high, peaked crown. In this 9.32ct specimen, the cut allows light to enter from all four sides, illuminating the natural “silk” within to create a soft, neon radiance. It is the ultimate choice for a statement cocktail ring or a one-of-a-kind collector’s trophy.
