4.93ct Gubelin Certified Brazilian Emerald in 1.70ctw VS1-VS2/G-H Diamond & Solid Platinum Ring (Comes W/$155,000 Appraisal) - This stunning ring is made of solid platinum, and boasts a magnificent 4.93ct octagonal-cut Gubelin certified Brazilian emerald. This piece has incredible investment potential, as Gubelin are the world leaders and most prestigious in colored gemstone grading worldwide. Brazilian emeralds can be considered to be in the top investment tier, as their fine color and good transparency make these gemstones highly sought after in the marketplace. Unlike Colombian emeralds which get their color primarily from chromium, Brazilian emeralds get their color mainly from traces of vanadium and usually have less inclusions then their Colombian counterparts. Colored gemstones are now fetching premium prices and breaking auction records, and the colored gemstone industry is now achieving annual retail sales of approx. $18 billion-$21 billion with many designers saying that the emerald is dominating the luxury jewelry market. This emerald is a stunning lush green color, and is gorgeously eye clean. The emerald is set in a 4-prong setting, with 18k yellow gold prongs to add extra security, as gold is less malleable than platinum. The ring is finished with approx. 1.70ctw genuine VS1-VS2/G-H diamonds, with baguette diamonds creating a halo around the emerald, round-cut diamonds at each corner of the square shaped table and round-cut diamonds lining the shoulders of the piece, showing wonderful attention to detail. The ring will be accompanied by the Gubelin report for the emerald, along with a $155,000 insurance valuation report in the winning bidder's name by a graduate appraiser. The table of the ring measures approx. 15.7mm x 15.3mm, and the band measures approx. 3mm wide. Ring size: 6.5 (WEIGHT: 9.1 grams)
