Gorgeous medium blue precision-cut lab sapphire in a Tiffany style solitaire!. The sapphire was precision-cut in the U.S. and set by lapidary and bench jeweler Phil Lagas-Rivera (AlternativesLapidary). The lab sapphire is flawless and cut in an elongated antique cushion design. It weighs 2.67 carats and has the dimensions 8.3 x 6.8 x 5.4mm. A nice size for a solitaire that packs a punch! The rough sapphire was made by Djeva in Switzerland and this color does not go dark. The ring is made of solid Palladium and is stamped "950Pd" on the inside. Palladium is a platinum group metal and will stay white without plating. It looks just like Platinum but feels lighter. The setting style is an integrated peg head solitaire to keep it lower and more comfortable on the finger, so this ring will not sit flush with a straight band (there will be a small gap). The prongs are split eagle-claws and are impeccably sleek and smooth. I am the original owner of this ring, it is gorgeous and in excellent condition, and it has never been resized. US size 5.5 and stamped "950Pd" on the inside of the band. Please contact me by email. I accept payment through PayPal G&S. USPS Priority shipping with full insurance and signature confirmation is included in the U.S. I am a private seller and all sales are final. Thanks for looking!
