The Crystal Cave has one of the largest collections of crystals, stones, minerals, etc. in South Florida and prides itself on carrying all natural specimens: no lab grown, dyed or enhanced stones here! (With the exception of Bismuth (kids love it!) and Goldstone for the properties of the copper.) Otherwise, be assured that ALL of our stones, crystals, jewelry, fossils, specimens, etc. etc. are all natural and formed within Mother Earth!
