The lot
Full description
A hand-graded cabochon of fancy moonstone from Karnataka, India, calibrated to the 13–26 mm working range. Sold as a single piece, weighed in carats, treatments disclosed.
About this lot
Origin: Karnataka, India.
Format: One specific cabochon, weighing approximately 15 ct, hand-graded from a parent lot of 3060 ct. Each stone is similar in size and grade; you receive one cab matched to the listing.
Size: 13–26 mm.
Weight: ~15 ct per piece.
Size note: Stones in the parent lot range widely from 13 mm to 26 mm (2.0× spread). The specific piece you receive may be on either end of that range — request a photo before ordering if size is critical.
Treatment: None. 100% natural, untreated material. Disclosed on every listing — that's the Atlas standard.
Suggested use
Pendant settings, statement rings, or display — adularescence and aventurescence show best in slow light.
