Description
This is another gorgeous green sapphire found within some of the older Kanchanaburi, Thai mines. Rare for its large size excellent color and clarity the sapphire is AIGS certified and weighs 4.38 carats. The large oval brilliant cut sapphire measures 11.0 X 8.3 X 5.32. Excellent cutting and clarity serve to deliver the rich evergreen color that is richly saturated throughout the stone. The color is strong primary green with a very faint secondary yellow hue. I found that my eye didn't pick up this yellow hue but it is noted in the photos. The sapphire's color saturation is a bit lighter than what is photographed as it actually has very exquisite evergreen color. Vibrant green flashes dance from within the stone which is prong set in a low position to offer added security, protection and comfort when wearing such a large stone. Complimenting the large stature of the sapphire is a wide banded 14K white gold ring with fine quality princess and baguette cut diamonds that are 0.70 carats total weight and VS2 G quality. The diamonds are elegantly present in sleek channel settings along the ring's shoulders. The ring weighs a substantial 7.0 grams of 14KWG and is a size 7 (resizing available..please note your size on the order form). This magnificent piece is offered by Jill Underhill of Color Symphony (http://www.colorsymphony.com) and will be shipped directly from their location in New Hampshire.
This gemstone (or gemstone that is part of this piece of gemstone jewelry) has been enhanced by traditional heat treatment. Traditional heat treatment is used to improve a stones color, remove color zoning/banding, and improve clarity. This treatment is considered permanent. The only way to tell if a colored stone has been treated is for the stone to be analyzed by a lab. Generally only gemstone laboratories have the equipment necessary to make a qualified judgement with any certainty.
Untreated gemstones are rare and should be verified by a lab independent of the seller. A good rule of thumb is to always assume a gemstone has been enhanced, unless valid certification from a reputable laboratory is available. No one that sells jewelry or gems should be doing appraisals, certifications, or analysis. It should always be an independent third party with no vested interest in the sale.
