Took forever to pick out a center stone and find the design. It is cast 14k white gold, has 16 purple amethyst side stones and an 8X6 oval Tanzanite that gets the purple hues depending on the lighting. i really love a tanzanite that gets purple hues in it. This is actually my first time buying everything separate and getting it put together and has definitely gotten me hooked in doing it. I think I am going to build a matching necklace and earrings, and after I get comfortable build our engagement rings.
