      Mystic Topaz is stunning to look at, but it actually isn’t really all that valuable as the multicolored effect is not found in nature.

    Hello! Compliments for your “semi precious” list.
    I am busy with learning more about gems.
    Would you know if one can order a big poster of main semi precious stones?
    I would be very grateful if you could help me. I would also like to find a basic course.
    I live close to Amsterdam.
    Many thanks and kind regards
