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.

his gemstone is a gorgeous vibrant, vivid, pure red lab-created spinel. It was grown via the Czochralski method. I purchased it in October of 2024 for $725. The stone is always a vivid red color and never goes brown or dark. My verification photo is in no way indicative of the color in real life. Pure, vivid red is a very rare and difficult color to find in both natural and lab-created gemstones. There are no purple, pink, or orange tones in this gemstone, only pure, vivid red. It is never muddy or unattractive. The stone does not have any feathers or fractures and or chips, nicks, or scratches. Under magnification, there is a polishing mark on the table. It has never been set. The price is $600. It was purchased from Eric Bardawil of House of Sylas via his website djeva.com Dimensions: 11.26 carats and 13.28 x 13.25 x 8.13 mm in diameter Photos/Videos (original vendor and my own): Link to the stone on djeva.com: https://djeva.com/collections/czochralski-red-spinel/products/pigeon-blood-lab-spinel-asscher-cut-11-26-carats https://imgur.com/a/HTSYt9g and https://imgur.com/a/NXJ3XT4 Fully tracked and Insured shipping is $25 within the United States. If it is less to ship an item, I will refund you the difference. Returns are not accepted because I am a private seller.
