My friend Jen made this necklace for my birthday. I believe the pendant is some type of... turquoise? I'm embarrassed to admit that I can't identify the stones that make this up (also, I confess, it took me three times to type "turquoise" correctly). Here's the jist: it's black with a dreamy shade of chartreuse throughout. When you hold it in your hand it is smooth and cool to the touch, like a stone. It's unlike anything I own and I love it. Everything about it reminds me of Jen and that makes it all the more special. Thanks, Jen, you are a dear friend.
