Tiffany & Co. 0.40ctw Blue Sapphire & Diamond Solid 18K Yellow Gold Vintage Ring - This lovely ring comes from one of the world's most celebrated house of gems and jewels, Tiffany & Co. The ring is finely crafted of solid 18k yellow gold, and is decorated with a delicate floral motif. The ring is embellished with a 0.20ct (approximate) genuine near flawless round-cut blue sapphire in the center of the piece, and finished with approx. 0.20ctw genuine VS1-VS2/F-G diamonds surrounding the sapphire, creating the petals. This is a truly magnificent find, as these pieces are rarely available in the second hand market, because most of these high commission pieces are in private collections, and become heirloom pieces. The inside of the band is stamped "Tiffany & Co." along with the gold purity. Ring size: 5. (WEIGHT: 2.2 grams)
