The 20 carat gem quality cushion cut tanzanite is set atop a split-shank diamond ring with a hidden-halo in platinum. Diamonds are set 3/4-way around making it appear as an eternity band, yet have the option to size the ring if needed. Ring contains 1.37 carat round diamonds. Item featured is subject to pre-sale as each ring is custom-made per tanzanite’s dimensions.
