I really loved the idea of the necklace, but I have to say that I was disappointed by it's size.  It's much more delicate than you might think - which is fine if you had an opportunity to pick it at a store.  It's pretty, but not amazing - that is really overselling it. I don't think it's worth the $50 I paid for it, as I bought it as a gift for a friend.  I think it's more about $25 or so, based on the size and the kind of chain that comes with it. I liked it, but I didn't love it.  I didn't send it back because I didn't feel like going thru the bother of returning, and finding something else.  I think the other thing about it, was that the necklace didn't come in a nice necklace box.  It was received in a little plastic ziplock bag inside a velvet-like bag. For $50, you would think that they would make it more presentable upon receiving it.  I had to find a box to put it in.  I could have gotten a gift box included for another fee, but it's my opinion that with that price, they should have included a nice box too. The stone itself was okay.  I thought it would be prettier.  It does change colors with what clothes you wear, which is a nice factor. It just didn't impress me as much as I thought it was going to. Bummer.
