The Unique Color-Shifting Quality of Alexandrite Gemstones Explained
In the world of precious gemstones, few are as captivating and sought-after as alexandrite. Named in honour of the Russian Tsar Alexander II in 1834, this gemstone was discovered in the Ural Mountains and has since held a special place in the hearts of gem enthusiasts and collectors alike.
The value of alexandrite gemstones is primarily driven by three key factors: rarity, size, and the intensity of its remarkable color change.
Alexandrite's most notable feature is its dramatic color shift, typically from green or blue-green in daylight to purplish-red or red in incandescent light. Stones with a strong, clear, and distinct color change command the highest prices. Larger alexandrite stones are exceptionally rare, and their value increases exponentially with size. For instance, a 16.53 carat alexandrite sold for $1.9 million at auction.
Rarity and origin also play a significant role in determining alexandrite's worth. Historically, the finest quality alexandrites are from the original deposits in Russia. Antique alexandrite jewelry, notably from the Victorian era, is more valuable due to scarcity and historical significance.
Clarity is another factor that influences the price of alexandrite, with clearer stones with fewer inclusions being preferred. However, clarity is often secondary to the quality of the color change.
A well-executed cut that maximizes the brilliance and enhances the color change effect increases value. Some alexandrites are commonly cut as cabochons due to inclusions, but faceted stones with strong color change are highly prized.
Authentication by reputable gemological labs confirming natural origin and quality helps assure value, especially for collectors and investors.
Despite its rarity and high value, alexandrite is part of the chrysoberyl family, which is separate from beryls. Chrysoberyls have good durability and a hardness of 8.5 on the Mohs scale. The color change effect in alexandrite is caused by chromium, the same coloring element that causes the red of ruby and the green of emerald.
Alexandrite is often found as a by-product in emerald mines, and it is now mined from Brazil, Myanmar, Tanzania, India, Madagascar, and Sri Lanka. However, rough alexandrite specimens over five carats in weight are scarce.
It's important to note that synthetic color change sapphire is a common simulant for alexandrite on the market, often found in antique pieces of jewelry. Therefore, certification from reputable gemological labs is crucial to ensure the natural origin and quality of alexandrite.
Clarity is poor in the majority of alexandrite stones, making them translucent to opaque. This, coupled with its rarity and high value, adds to its allure and mystique.
According to Russian legend, wearers of alexandrite reap benefits including good luck, good fortune, and love. The vibrant red and green colors observed in alexandrite mirror the colors of the national military of Imperial Russia, further enhancing its historical and cultural significance.
Since the 1960s, alexandrite has been successfully synthesized in laboratories, but the beauty and rarity of natural alexandrite continue to make it a coveted gemstone among collectors and jewellery enthusiasts. Prices for fine alexandrite specimens above a single carat can rival or surpass fine quality rubies, emeralds, and diamonds, making it a truly exceptional and valuable gemstone.
