Natural Spinel – 6.23 ct | Octagonal cut | Deep black

A natural spinel from Madagascar in a striking octagonal cut, characterized by a deep black hue and a homogeneous appearance. The clean, geometric lines of the cut lend the gemstone a modern, powerful radiance. The surface exhibits even light absorption with a subtle, silky luster that elegantly underscores the dark color.

There is a small nick on the lower edge. This defect is localized and only slightly affects the overall appearance of the stone, but should be taken into account when setting it.
