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!

This ring is a Ken & Dana Design crafted piece. Take a look at their website to see their work. The ring was sent to eBay Authentication and has been successfully authenticated. I will include all the paperwork I originally received with the ring as well as the eBay authentication cards. All details are listed under the item specifics. The platinum setting is modern and minimal, but extremely well made and solid. It makes the cushion cut stone the center of attention and the claw prongs elevate the piece. I was able to stack this ring with a ring cuff and wedding band (cuff and band not included). This is an absolutely beautiful engagement ring, but my husband purchased a new ring for me for our anniversary. SPECS: Brand: Ken & Dana Designs Main Stone: IGI Cert. Lab Grown Diamond (Cushion cut) Main Stone: 2.02ct, 6.9mmx7.2mm, G/VS2 Band: Platinum Size 5.5 Price is firm, but it includes free insured shipping within the US. All sales final. I accept PayPal or Venmo. If you get a Loupetroop error with messaging, you may email me at laurakos@yahoo.com
