Blue Topaz Heart - 14ga Threaded end - Yellow GoldWhen I chose this frosty topaz heart from the Kiwi stone inventory, I was curious to see how they would set it because we always let them freestyle the pieces we buy. It ended up in this beautiful yellow gold six prong setting with texture that can be seen through the stone.
