Abstract
not only represent the largest portion of all mineral species in terms of chemical classification, but they are also a major portion of the materials used as jewelry gemstones. The qualification “jewelry” implies “utilitarian,” if one can call adornment that, and leaves out rare and unusual collector gems. It means that this type of gemstone has a hardness and/or toughness to withstand being worn or used somehow, and a color and/or diaphaneity to be attractive to the viewer. Ironically, two of the hardest and best-known gem MARK MAUTHNER Postfach 0035 8010 Graz Austria mmauthner@gmail.com All photos by Mark Mauthner; unless noted, specimen ownership is either private or unknown
