What a shame that I must part with this stone! This is a lovely medium dark (slightly darker than images) blue untreated sapphire from Reddestone Creek, NSW, Australia. Cut in John Bailey's Sorrel Custom pattern by talented American cutter David Dawson. Weighs 1.00 ct and measures 5.9 x 6.6 mm. Perfect provenance - cut by David from rough purchased directed from Andrew Lane at AussieSapphire.com. A certificate from Andrew for the original rough indicating the untreated status provided with the cut stone. Money back if you're not happy and treatment status completely guaranteed! $6.00 shipping via USPS priority mail in USA. 7-day return policy once you receive the stone.
