TWENTY-ONE UNMOUNTED BLUE GEM SAPPHIRES Mixed faceted cuts, 39. 7 cts. TW. Note: Unmounted gemstones from the estate of Harry B. Roth, 1913-2008, a longtime member of the Diamond Dealer Club of N.Y., a connoisseur and avid collector of fine colored gems. The bulk of the collection dated from the 1960"s and 1970"s, and predates many modern enhancement processes. While gemological reports have been secured for many of the lots, some indications of gem origins have been taken from parcel notations. Additional tests would be needed for positive identification of origins and treatments."
