from jonathon who cuts the special AVC, VINTAGE square stone, f color , and 8.5 mm. I just got this and dont want to go thru the return process, trying to fund a project and the stone is just a tad larger than what I need. my loss is your gain, mint new condition, beautiful white color. his stones look like his diamond counterparts. private seller no returns, be sure to love this beauty. huge deal on this price
