Selling an absolutely breathtaking designer engagement ring with top-tier specifications. Total original retail investment was $3,400 ($1,900 for the hand-selected center stone + $1,500 for the Fana setting).Because Asscher cuts feature wide, open steps, stone quality is paramount. This diamond was selected for its elite D color and VVS2 clarity, making it exceptionally crisp, bright, and ice-clear.The setting is a stunning piece of designer artistry by Fana, sourced directly through International Diamond Center (IDC). It features a heavy, high-quality 14k white gold split-shank band. Tucked elegantly beneath the center stone basket profile are two vibrant peek-a-boo rubies. The ring is in excellent pre-owned condition. Skip the retail markup and secondary custom design fees on a genuine piece of luxury bridal jewelry!

Hi, I'm selling a near colorless 3ct (9.5x7.5mm) elongated old mine cushion cut moissanite ring with moissanite side stones in 935 argentium silver. Hi, no bad juju. I'm selling it because I haven't worn it more than once and it's just been sitting here. I purchased a lot of beautiful rings in different cuts and styles right before my weight loss journey. Bad timing for my wallet since I didn't realize how much of a difference the end result size would be. Payment can be through PayPal, Venmo, or Cashapp. Since I am a private seller, there will be no return, refund, or exchange. I hope you understand. So please feel free to ask any questions and concerns before making the purchase. I will pay for the shipping cost using USPS that will come with tracking. US sale only, sorry.

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.
