The 2.81 carat oval diamond , my second purchase from Ritani, is the most beautiful diamond I've ever seen outside of an expensive showcase and is the type of diamond I thought I could never afford to own. Ritani made it possible. I did the research using the diamond certificate # and this exact stone was on 2 other sites, one at $595 more, the other $716 more. The stone arrived by Fedex exactly on the date they said it would. I collect gemstones and create jewelry and this diamond is the star of my collection. I use to think Moissanite was a great alternative, but no Moissanite in my collection could match this large oval real diamond.
