My heart did flip flops when I saw it online, and that rarely happens, so I was disappointed that the coloration isn't as depicted. I don't know if it's because I got it on waitlist, and they rushed production. I love it enough to keep it, and will wear it a lot.
It looks like amethyst stones with a silver drusy. It's comfortable, but if you have to open it, it can pinch your finger.
I love Marianna & Richards designs and craftsmanship.
