Gorgeous Setting

If you like rose gold and are looking for a 6-pronged setting, I highly recommend this ring. The sparkle of the diamonds on the band really set off the centre stone, and the intricate hand engraving gives the rose gold its own sparkly, glitter-like quality. The six prongs secure the centre diamond and make it look a bit larger. I'm very happy with my choice and feel like I got a great value, too.
