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.
