Okay truth time. I had NO clue that this existed. This is Siberite Tourmaline. Found in well, Siberia this purple pretty gets its color from mineral rich environments rich in Manganese.

This specimen is from Siberia from the Malkhan district in the Transbaikal (Zabaykalsky Krai) region.

Alexandrite

Did you know?

That Alexandrite is a mineral that can change color depending on different light sources.

The term Alexandrite came from Emperor Alexandria ii.

Alexandrite that comes from the Ural Mountains of Russia is colored green in daylight to red in incandescent light.

Other varieties of alexandrite may be yellowish or pink in daylight and a columbine or raspberry red by incandescent light.

This chameleon-like color shift is the result of its uncommon chemical composition which includes traces of chromium, the same coloring agent found in emerald. The unlikelihood of these elements combining under the right conditions makes alexandrite one of the rarest and most expensive gemstones on Earth.

The alexandrite mined from Russia’s famed deposits set the quality standard for this gemstone. Today, most alexandrite comes from Sri Lanka, Brazil, and East Africa, generally paling in comparison to the vivid colors of Russian gemstones.

With a hardness of 8.5 on the Mohs scale, alexandrite is softer than sapphire and harder than garnet—the other gemstones that can change color. However, due to its scarcity, alexandrite is more valuable than most gemstones, including rubies and diamonds.

Depending on lighting with the spessartine specimen it lights up and flashes deep orange red fire. I have been asked to display at the Denver Gem & Mineral Show this year and I’m looking forward to putting a display together. #spessartine #spessartinegarnet #garnet #garnetjewelry #geology #Crystal #gemstone #rockhounds #rockhounding #geology #geologist #gemologist #mineralshow #minerals #naturalgemstone #instacrystals #crystalshop #gemshop #crystals #gemstones #gemporn #mineralporn #crystalporn #geologyrocks #fineminerals #finegemstone #crystalline #geologypage https://www.instagram.com/p/Cp8klP4vr1e/?igshid=NGJjMDIxMWI=
