The top in the aqua line up is unheated tanzanite. It has a really neat steely green/gray/blue combination.
Amazing collection of emerald cut and similar cut stones!
Oh yay! I can definitely play in this thread!! Emerald cut is my favorite shape and anything similar. Some of these aren’t straightforward emerald cuts but very similar styles. I’ve got 4 tourmalines, 2 garnets, 2 sapphires, 2 aquamarines, 1 spinel, 1 heliodor, 1 tanzanite, 1 sunstone, & 1 diamond! Oh and 1 emerald snuck in! Oddly, I only have two rings with the shape, a rhodolite garnet & spinel with diamonds. I cannot wait to see what others post!
