I’m a novice gemology student. I’m traveling to Turkey in the near future and I’d love to know more about Turkey’s gemstones. What might I find on my visit? I’ve got my gem identification book ready to go. Any information would be greatly appreciated.
One of the most well-known of Turkey’s gemstones is diaspore. Although this rare gemstone can be found in other locations around the world, including Massachusetts and Pennsylvania, it can be found notably in Turkey’s Mugla Province in the southwest. Typically colorless but also found in yellow, pink, or brown, diaspore is notoriously difficult to facet into jewelry pieces.
Editor’s Note: Diaspore stones over 2-3 carats from a single location in Turkey may display color changing. These gems have the trademarked name “Zultanite.” However, gemologically and mineralogically speaking, these gems are diaspore.
Unusual Gems From Turkey
Colemanite is normally colorless and difficult to cut. This unusual specimen with orange highlights was found in the Mustafakemalpascha mine in western Turkey.
