I was looking for ammolite for my husband. Other websites are not always clear about whether they have genuine ammolite or simulated ammolite. I have purchased from GemSelect before and trust that the stones are genuine. Finding the stones I want is easy, and I love all of the search filter options!

Hello: You do have good website. Vast majority of folks would buy the Gems for its spiritual, physical / energy level, emotional level positive aspects. You have only very brief mention of this aspect of each Gem ..may be you can add little bit more about ways to leverage the beneificial effect of each gems i.e. some practical tips.ThanksRupen Patel
