June 2009, Vol. 5, No. 3
Most gems are natural minerals, which, although scarce and small, have a major impact on society. Their value is directly related to proper identification. The determination of the species is key, of course, and must be done non-destructively. This is where classical tools of mineralogy come into play. However, other issues are paramount: Has this gem been treated? Is it natural or was it grown in a laboratory? For certain varieties, being able to tell the geographical provenance may enhance value considerably. These issues necessitate cross-linking the formation of gems with their trace-element chemistry. These unusual mineralogical and geochemical challenges make the specificity of gemology, a new and growing science, one of the possible futures of mineralogy.
