Geological Formation and Sources
Alexandrite is a rare gemstone that forms under specific geological conditions, making its natural occurrence exceptionally limited. It is a variety of the mineral chrysoberyl, which is composed of beryllium aluminum oxide (BeAl₂O₄). What distinguishes alexandrite from other chrysoberyl varieties is the presence of trace amounts of chromium and vanadium, which are responsible for its remarkable color-changing phenomenon. These elements interact with light in a way that causes the gemstone to appear green in daylight and red or violet in artificial light.
The formation of alexandrite requires a unique combination of temperature, pressure, and chemical composition. It typically forms in metamorphic rocks, particularly in regions where granites and schists intersect. These environments provide the necessary conditions for the crystallization of beryllium and aluminum compounds, which are the building blocks of chrysoberyl. The presence of chromium and vanadium, which are not commonly found in high concentrations, further enhances the gemstone’s value and rarity.
Historically, the most significant source of natural alexandrite was the Ural Mountains of Russia, where the gemstone was first discovered in the 19th century. The Malashova Mine in the Ural Mountains was one of the primary sources of alexandrite during this period, producing some of the finest examples of the gemstone. These Russian stones are particularly prized for their vivid color change and high clarity. However, due to the depletion of these mines and the limited supply of natural alexandrite, the Ural Mountains are no longer a major source of the gemstone.
In the mid-20th century, new sources of alexandrite were discovered in Brazil, specifically in the Hermatita region. Brazilian alexandrite is known for its impressive color change, with the red hues in artificial light often being more vibrant than those of Russian stones. While these Brazilian stones are not as valuable as their Russian counterparts, they have played a crucial role in meeting the global demand for alexandrite. The discovery of alexandrite in Brazil has allowed for the continued production of jewelry featuring this rare gemstone, ensuring its availability for future generations.
In addition to Russia and Brazil, alexandrite has been found in other parts of the world, including Sri Lanka (Ceylon), India, Tanzania, and Madagascar. Each of these locations produces alexandrite with slightly different characteristics. For example, alexandrite from Sri Lanka tends to display a rich green in natural light and a reddish-brown in artificial light, while Indian stones are praised for their superior bluish-green hues in daylight. The largest pieces of raw alexandrite have been known to come from mines in Tanzania and Madagascar, further highlighting the global distribution of this rare gemstone.
The geological rarity of alexandrite is one of the primary factors that contribute to its high value. Natural alexandrite is so scarce that most of the gemstone available today comes from older, period pieces or from synthetic sources. The limited supply of natural alexandrite, combined with its unique color-changing properties, has made it one of the most sought-after gemstones in the world. As a result, alexandrite remains a symbol of exclusivity and luxury, continuing to captivate gemologists, jewelers, and collectors alike.
