Here at Riley & Riley we love diamonds and were very amazed to hear about two particularly spectacular diamonds that will be auctioned through Sothebys in Geneva next month.

The first is a round brilliant cut weighing in at a huge 51.71 ct! This makes it the second largest D Flawless round brilliant cut diamond to ever appear at auction. The largest was also sold by Sothebys, and is the only known round brilliant in existence to be over 100ct.

The second stone is oval in shape and weighs 50.39ct, it shares the same characteristics as the round brilliant diamond, and is also the second largest of its shape.
