Blue Nile - An 18k Gold & Diamond Ring, American 2020, four claw-set with a brilliant cut diamond, stated to weigh 1.52 cts, on a plain tapered shank, stamped 18k. Assuming that there is Gem Lab Diamond Certificate stating:- Color: F (Colourless) Clarity: Si2 ( Slightly Included) I do not advise selling the Ring without the GIA or EGL Diamond Certificate if one is available & I am happy to review my estimates
