Tanzanite Center
At the top of this ring, a 2.50 carat cushion cut tanzanite sits in a four prong setting made from 18k white gold. All of the prongs originate from a single point directly below the main setting, and they angle in slightly on the way up to complement the elegant shape of the center stone.
The rich color of the tanzanite, with its deep blue accented with hints of purple, makes for a dramatic centerpiece while also enhancing the uniqueness of the design. Tanzanite is a relative newcomer to the world of fine jewelry, but it’s rapidly increasing in popularity and makes for a wonderful alternative to diamond or sapphire in an engagement ring.
Diamond and Milgrain Accents
On either side of the tanzanite, a trillion shaped diamond is chevron prong set within the opening created between the two strands of the split, criss-cross shank. These diamonds combined total 0.25 carats, and they provide just the right amount of contrast with their brilliant white sparkle, helping to enhance the beauty of the larger blue stone above.

Both strands of the shank are also bright cut set with round diamonds, and milgrain beading frames these accent stones for a lovely hint of vintage flair. The diamonds continue down nearly to the bottom of the ring, leaving just enough space between them to accommodate a sizing bar, and they highlight the elegant movement of the shank design nicely as well.
