Do you really know what you are buying or selling?
Every day, thousands of gemstones and minerals are sold under a variety of commercial and fancy names. Some stones are treated, completely man-made, or sold under a misleading name that makes them appear to be something other than what is promised. Without proper knowledge, it is difficult to determine whether a stone is a Gem or a Scam.
