I just started going into this shop about a week ago. I had such a good experience I had to go back again this week for a closer look. The owners are very nice and helpful and very knowledgeable. Should be able to answer any questions you may have on rocks or any thing else in the store. Have the owner demonstrate there magic eggs very cool to see and the price is cheap you just might have to take one home. Either way this is a great shop worth a look.
