The Asteria engagement ring delivers the perfect balance of sparkle and style. The yellow gold band is luxuriously decorated with diamonds that glisten as the swan neck envelops the cushion cut centre diamond. The gallery rail is also lined with tiny diamonds that add a unique and subtle glamour, the ring lavishly set with a total of 0.25ct of diamond melee.
