I’ve been a Rockology customer for 9 years. These aren’t just pretty mineral photos, they are stunning in person and the photos are true to what you see. I’m always amazed! As as dealer at and devotee of the major gem and mineral shows, I can tell you Dan and Shelley offer quality specimens at a very reasonable price, and are tops at being honest and reputable.

Best selection, outstanding product, amazing prices and the best customer service. Dan and Shelley provide that personal touch when it comes to customer service and the most genuine people around. They are definitely great people to do business with and I look forward to doing more.
