For sale: The most exquisite antique cushion cut lab diamond. It is 3.03 ct I VVS2 measuring 10.38 x 7.41 x 5.09 mm. It throws gorgeous flashes and pastels and has the perfect color for an old cut in my opinion. I purchased this on here and never got around to setting it. I am only selling because I purchased a larger one and can't justify keeping both. Happy to send more photos and videos if needed. All sales final as I am a private seller. Feel free to make me an offer. Thanks for looking!

We were working with a jeweler who messed up my wedding band and it no longer sat flush with the oval engagement ring. We ended up switching out the engagement ring with a new jeweler. He would not refund us for the original. I'm looking to sell the loose stone - our loss is your gain as we obviously paid retail value (think brilliant earth prices - $5k ish for this rock). Price includes insured shipping - signature required. Please email me carolgoconn@gmail.com Stone Specs: Carat Weight: 2.57 ct Shape/Cut: Oval Brilliant Measurements: 11.06 × 7.79 × 4.80 mm Color Grade: E (near colorless – icy white) Clarity Grade: SI1 (completely eye clean) Polish: Excellent Symmetry: Excellent Fluorescence: None
