Rare, Large Yellow Star Sapphire

Sri Lanka
The alluvial gem gravels of Sri Lanka were the source of this rare, large oval cabochon, a high-domed yellow sapphire which displays a strong central star effect and a medium yellow hue. The optical phenomenon of asterism is very rarely seen in yellow sapphires and particularly not in stones of this size. This is a unique offering for the serious collector of phenomenal gemstones (those gemstones which possess optical phenomena). Weighing approximately 75.43 carats and measuring 22.62 x 19.74 x 16.19mm mm

Footnotes

Non-heated yellow sapphires are scarce and this sapphire shows no indication of heat-treatment.
