I'm selling a size 7.5 US ring. The main stone is a lab created diamond, D VS1 2.23ct oval cut and the bow tie is very minimal. It's in a platinum tulip pave setting. It will come with the IGI paper. The oval cut was my dream diamond shape and I purchased this for myself. But unfortunately, when I received it, I was too scared to wear it out, in case I'd damaged it. No bad juju. I purchased a lot of beautiful rings in different cuts and styles right before my weight loss journey. Bad timing for my wallet because soon after receiving most of them, I've already lost some weight. 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.

Hi, I'm selling a size 7.5 US ring. The main stone is a 2.39ct Old Mine Cut lab diamond with 14k white gold. There is no noticeable warmth and eye clean. Beautiful chunky brilliance! I knew the band was going to be white gold, so I didn't want a warm stone that would look off with it. I don't have a certificate. It's reflected in the price. When I was looking for the OMC cut, I was more concerned about the culet and to clearly see the chunky center pattern that I love with the OMC cut. For an antique cut, it still looks well with the modern plain band and hidden halo. I've only worn it once or twice, so it still looks pretty new. One of my favs. This would be the one I would keep, if I had to pick. No bad juju. I'm selling it because I've barely worn it 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 Since I am a private seller, there will be no return, refund, or exchange. I hope you understand.

I'm selling it because I didn't get to wear it and it's too pretty to be sitting here. It seriously look brand new.
