If I had received the earrings pictured, I would have been floating on air - what GREAT deep purple color - but what I got was washed-out-looking stones.  My husband bought me these for our 25th anniversary because I'm an amethyst freak and have quite a few pieces of good, dark purple stones.
On the up side, if you don't really care about the tint, the earrings are very cute, fairly sparkly, and are almost unnoticeably light on your ears. I'll probably keep mine and wear with more casual outfits, but it's too bad they aren't as pretty as pictured in the ad.
