It is estimated that more than 98% of the sapphires on the market today have been heat-treated, primarily to improve color. It is so common a treatment that it is completely accepted by the jewelry trade, and barely even mentioned. Untreated sapphire, as is noted on the accompanying AGL report, is scarce. When it comes to certifying that gemstones are untreated, there are very few labs that are completely trusted. The lab I always use for colored gemstones is one of the most respected labs in the world, American Gemological Lab, or AGL. This lab is commonly used by the likes of Christies and Sothebys, for the authentication of some of the most expensive gemstones in the world. I invite you to visit AGL's website, or even place a quick call to the jewelry department of Christies or Sothebys, and ask for a reference for AGL. They have won many of the top awards and accolades in the world of gemological research. The lab report accompanying this ring is from AGL, certifying that the sapphire is completely untreated, and of Cambodian origin.
This glamorous Edwardian ring weighs 7.9 grams. The center sapphire, a vivid blue color, oval mixed-cut, weighs approximately 2.60ct, determined by formula. It is surrounded by a halo of 10 old mine-cut diamonds, each approx 0.17ct, of very good brightness and sparkle, an estimated H-I color and SI1-SI2 clarity. There is an unobtrusive surface chip on one diamond, observable under the microscope and commensurate with the age of the piece. One small, old mine-cut diamond, approx 0.025ct, is set on each shoulder of the mounting. The gallery supporting the ten diamonds is platinum-topped, and the heavy band is 14kt gold, stamped and tested. The ring is size 6.25, and can be easily resized one or two sizes. Inside the band is an old engraved inscription, "J. H. to J. M.", which can be easily removed. The ring is in excellent condition, and will arrive in a black velvet ring box.
The ring will be accompanied by AGL report # CS 1072749. For security reasons, only a copy of the AGL report will be sent with the ring at time of purchase. The original laminated report will be sent under separate cover once the purchase is complete and verified.
