So I'm looking to invest in a nice aquamarine ring (since its my birthstone ^__^)... I LOVE the Tiffany stack version but I don't like wearing yellow gold and I don't want to pay that much for silver. I do love the design though its unique in how the aquamarine is cut (at least from the typical ones I've seen around). Any one have any suggestions for unique aquamarine rings and where I could find some?
