An elegant and beautiful, natural oval cut tanzanite stone, mounted in a plumb 18k white gold handmade diamond mounting. The mounting contains 34 white and bright diamonds that are clean to the naked eye. The diamonds are custom cut to make this ring a unique one, not to be seen on any other fingers. My wife designed this ring, so I am positive you will not see it anywhere else. As I mentioned before, tanzanite is controlled by a syndicate analogous to the DeBeers syndicate, and prices have been fluxuating since they took over. This ring is sure to delight the wearer forever.
