Gemstone Education

There are a tremendous variety of colored gemstones–literally hundreds of different gems.  Even individual colored gemstone types–like tourmaline–can be subject to an amazing array of variation.  In part because of this variety, and in part because there has been no single push for consistency and education in the colored gem market, a lot of confusion and misinformation persists.  In this section of the Earth’s Treasury website I’ll post articles on a variety of colored gemstones and provide links to more detailed information and any sources I have used in creating my own information page.
