Let’s look at the fascinating history of raw Alexandrite, its origin, unique features, uses, and how you can distinguish natural Alexandrite from synthetic one.

Fascinating History of Alexandrite and Its Origin

Raw Alexandrite was initially discovered in the Ural Mountains of Russia in the 1830s. Today, this rare gemstone is also found in Sri Lanka, Madagascar, Tanzania, Myanmar, India, and Brazil. The mineralogist Nordenskiold discovered the exceptional color-changing stone near the Tokovaya River in the Ural Mountains. The precious stone caught the country’s attention because of its red and green colors, which mirrored imperial Russia’s military colors.

The precious stones were named after the then-future Czar of Russia, Alexander II. In 1830 when the never seen color-changing gem was discovered, Alexander II was still young, 1818-1881. The first alexandrites found in the Ural Mountains were very fine and high quality, and they displayed fascinating hues and spectacular color changes. However, the gem did not last forever. Today Alexandrite comes from Sri Lanka, Brazil, and Tanzania. 

The newer alexandrite deposits still possess fine-quality stones, but few matches the color quality change and hues of the 19th century Ural Mountains alexandrite. This has made the Ural Mountains’ Alexandrite remain the quality standard for this precious stone up-to-date.

Alexandrite Unique Features 

Raw Alexandrite is a variety of chrysoberyl gemstones, a hard, challenging, durable, precious gem. Here are some unique features of the natural Raw Alexandrite:

The “alexandrite effect,” or the color-changing phenomenon seen in Alexandrite, is ascribed to the complex way the mineral absorbs light. The chromium content in Alexandrite displaces the transmission of green and red right equally, making it change colors when placed under different light sources or viewed from different angles.

Clarity and Cut: Clarity is essential when grading raw Alexandrite. A high clarity rating increases the value of the gemstone. It is worth noting that a natural raw alexandrite or a naturally occurring alexandrite is not clean and is best suited for cabbing. Nonetheless, the ability of Alexandrite to change color has a significant effect on its value than clarity.

Our Final Thoughts

Alexandrite is one of the rarest and most expensive gemstones, actually almost the same as diamond. Its scarcity and high demand provide a good market for the lab-made Alexandrite, which was introduced in 1971 and had almost similar features to the raw Alexandrite. It is worth noting besides the inherent green color exhibited by all-natural Alexandrite, a sizeable clean alexandrite is rare and extremely expensive. Therefore, such Alexandrite is likely to be synthetic or a simulant.

When looking to buy alexandrite gemstone, we recommend first considering whether you need a natural alexandrite, a synthetic (a lab blend alexandrite, almost similar to raw Alexandrite), or a simulant (artificial gemstone replicating real Alexandrite). The next step is to find a reliable gemstone seller who can deliver what you desire.
