Round Lab Diamond 18K Rose Gold Knife Edge Solitaire Ring
An exceptionally beautiful ring with a mesmerising round solitaire fitted securely in a four-clawed white gold mount on an 18k Rose gold band. The solitaire is gemologist certified and lab-grown.

As you view the ring from the side, you see the mount and the band forming three pretty triangle shapes that further give the ring a delicate charm. This is a splendid piece of jewellery that makes a style statement with simplicity combined with a dash of sparkle.
