Spinel is perhaps the most underestimated gemstone in the world.
This 4.67 cts Spinel of Black hue from Sri Lanka was selected for the Skyjems Archive not as an afterthought, but as a deliberate acquisition. It is entirely unheated and untreated — a distinction that places it in the top fraction of the global Spinel supply and is the single most important value driver in the collector market. Sri Lanka — historically known as 'Serendib' — has been the world's premier source of fine sapphire, spinel, and chrysoberyl for over two thousand years.
