1 carat equivalent, Forever Brilliant Charles & Colvard Moissonite center stone in palladium bezel solitaire setting (size 6) from Moissonite & Co. Piece was purchased in mid-2013 and worn until the end of 2017. The setting allows for almost any kind of band to sit flush next to it. I would also be willing to sell the bands in the photos (band 1 - palladium with 2 ethically sourced diamonds, custom made to fit with diamonds flanking each side of main engagement ring stone from artist on Etsy, band 2 - vintage 1960's channel set diamond band in platinum). All rings are a size 6.
