Video: https://imgur.com/a/4jsnssS This is a fanstastic piece in! It is a vintage diamond ‘daisy’ style of ring with a large 2.59ct yellow old mine cut diamond in the center. The diamond is GIA certified as W-X, which is all the way at the bottom of the diamond color scale. So it is still yellow, but no where near the same costs of a fancy OMC Diamond of this size. Having said that, it was very expensive to purchase even wholesale. The center stone is surrounded by an additional 2 carats of white old mine cut diamonds of very high quality, both in clarity and color. The diamonds are set in 18k yellow gold. The shank and shoulders have additional very neat details that only add to the piece. The ring is currently is size 5.75, but it can be resized easily at no additional cost. For payments, I use Paypal invoices (Goods & Services). My direct contact is cdvii@vucetadiamonds.com
