Beautiful Druzy Stone w/ rhinestones w 18 in chain

This beautiful blue colored Druzy piece with purple accents is "genuine stone" but I don't know what kind of stone it is. The Druzy part is surrounded by tiny rhinestones. Beautiful piece! I can't get a good picture of it. :/ Please check out my bundle discount purchase two or more items and get 20% off!
