Every gemstone in the Skyjems Archive was selected because it represents something the mass market has overlooked — a geological phenomenon whose rarity is defined not by marketing but by the finite circumstances of its formation.
This 0.85 cts Gemstone of Yellow 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 Gemstone 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.
