This ring is one of a kind! And definitely a centerpiece that cannot be missed. I originally bought the stone through Poshmark that was set in a temporary sterling silver mounting.I reset the the diamond into a custom 10k white gold (size 7) band that is hugged in 1 ct total channel set mount. The piece is stunning to say the least. Inside you will see the band has the carat weight of diamonds (6.75cttw), 10k and cert number. (pictured above) 5.70ct center 1ct semi mount Comes with IGI certificate (center stone) and was obviously already authenticated through Poshmark. NOT ZALES- just for view
