History and Lore: The Imperial Connection
The story of Alexandrite is inextricably linked to the Russian Imperial family and the name Alexandra. The gemstone was discovered in the Ural Mountains of Russia in the early 1830s, a period marked by the reign of Tsar Nicholas I. The discovery occurred near the Tokovaya River in the emerald mines of the Ural region. According to historical accounts, the stone was first identified by Finnish-born mineralogist Nils Gustaf Nordenskiöld, who initially mistook it for an emerald due to its green hue in daylight. The stone's true identity was confirmed upon examination, revealing its unique color-changing property.
The gemstone's connection to the name Alexandra is cemented by its namesake. The stone was named "Alexandrite" in honor of the future Tsar Alexander II, who was born on the same day the stone was discovered, April 23, 1818. Alexander II was the son of Tsar Nicholas I and was heir to the Russian throne at the time of the stone's discovery. The naming of the gemstone after the young Grand Duke Alexander (later Tsar Alexander II) was a tribute to the future ruler. The name Alexandra, the feminine form of Alexander, thus carries a direct historical link to this Imperial gemstone. The name Alexandra itself has a long history, with variants appearing across many languages and cultures. The name's origin is the Greek Alexandros, meaning "defender of mankind," a title of great power and significance. In the Russian context, the name is associated with the Imperial family; for example, Alix of Hesse, a German princess, was renamed Alexandra upon joining the Russian Orthodox Church and became Empress Alexandra Feodorovna, wife of Tsar Nicholas II. This historical intertwining of the name Alexandra with Russian Imperial power and the discovery of Alexandrite creates a potent symbolic connection between the name and the gemstone.
The lore surrounding Alexandrite is rich and deeply rooted in Russian culture. Its most celebrated characteristic, the dramatic color change, was often interpreted as a symbol of the duality of Russian life—the green representing the forests and the red or purple representing the blood of the Russian people or the fires of revolution. This chameleon-like quality led to the belief that Alexandrite could bring good fortune and balance to its wearer, harmonizing the different aspects of life. The stone became a symbol of good omens and was believed to be a bringer of luck, a notion that persists in some modern metaphysical beliefs. The gemstone's rarity and its initial discovery in the Ural Mountains, a region known for producing some of the world's finest gemstones, further enhanced its prestige and desirability among the Russian aristocracy and, later, the global elite.
Geological Formation and Sources
Alexandrite is a variety of the mineral chrysoberyl, with the chemical formula BeAl₂O₄. Its unique color and color-change phenomenon are the result of trace amounts of chromium (Cr³⁺) substituting for aluminum in the crystal structure. The presence of chromium is responsible for the stone's absorption of specific wavelengths of light, causing the observed color change. This geological process requires specific conditions of temperature, pressure, and chemical composition, making natural Alexandrite exceptionally rare.
The primary and most historically significant source of Alexandrite is the Ural Mountains of Russia. The mines in the region, particularly those in the Ilmensky Mountains and near the Tokovaya River, produced the finest-quality Alexandrite of the 19th century. These Russian stones are renowned for their vivid green-to-red color change and are considered the benchmark for the gemstone's quality. However, the production from these classic Russian localities has significantly declined over the past century, and high-quality material from these sources is now extremely rare and commands premium prices.
In the late 20th century, new sources of Alexandrite were discovered, expanding the global supply of this gemstone. Significant deposits were found in Brazil, particularly in the states of Minas Gerais and Bahia. Brazilian Alexandrite can exhibit a wide range of colors and color-change intensities, from light green to bluish-green in daylight and pale pink to deep raspberry red in incandescent light. While some Brazilian material rivals the quality of the Russian stones, it is often found in larger sizes.
Other notable sources of Alexandrite include Sri Lanka, which produces stones with a more bluish-green to violet color change, and East Africa (Tanzania, Zimbabwe). East African Alexandrite is known for its strong color change, often from a distinct green to a vibrant red or purple. Some sources also mention deposits in India and Myanmar. The geographic distribution of Alexandrite sources is a key factor in its value, with Russian Alexandrite historically holding the highest prestige and price due to its legendary color change and historical significance.
Gemological Properties
Alexandrite is prized for its exceptional physical and optical properties, which make it a durable and captivating gemstone for fine jewelry.
Crystal System and Hardness: Alexandrite crystallizes in the orthorhombic system. On the Mohs scale of hardness, it registers between 8.5 and 9, making it one of the hardest gemstones after diamond, corundum (ruby and sapphire), and topaz. This high hardness confers excellent durability, making it resistant to scratching and suitable for a variety of jewelry settings, including rings and bracelets that may be subject to daily wear.
Color and Color Change: The most defining characteristic of Alexandrite is its pleochroism and color change. Under natural daylight (which is rich in blue and green wavelengths), the chromium ions absorb the red and yellow portions of the spectrum, resulting in a green to bluish-green appearance. Under incandescent or tungsten light (which is rich in red wavelengths), the absorption spectrum shifts, allowing more red light to pass through, resulting in a red, purple, or raspberry-red color. The intensity and quality of this color change are the most critical factors in determining an Alexandrite's value. The most sought-after stones exhibit a vivid green to vivid red change with a high degree of saturation in both colors.
Clarity: Alexandrite is typically found as a transparent to translucent stone. Inclusions are common and are often used by gemologists to distinguish natural Alexandrite from synthetic or imitation stones. Typical inclusions may include long, parallel tubes or needles, often associated with the crystal growth process. Some inclusions may be visible to the naked eye, while finer specimens are eye-clean. The presence of inclusions can affect the stone's transparency and light performance, but they are also a hallmark of natural origin.
Cut: Due to its rarity and value, Alexandrite is often cut to maximize carat weight and to showcase its color change. Common cuts include oval, round, pear, and cushion shapes. The cut is crucial for displaying the stone's unique properties; a skilled lapidary will orient the crystal to ensure the best color change is visible from the top of the stone.
Refractive Index and Specific Gravity: Alexandrite has a refractive index ranging from approximately 1.746 to 1.755. Its specific gravity typically falls between 3.71 and 3.73. These gemological properties, along with its characteristic inclusions and color change, are essential for accurate identification.
The following table summarizes the key gemological properties of natural Alexandrite:

Symbolism and Metaphysical Beliefs
The symbolism of Alexandrite is as multifaceted as its color change. Historically and culturally, it has been associated with duality, balance, and transformation. In Russian lore, the stone was seen as a reflection of the nation's character—green like the forests, red like the blood of its people. This dual nature led to its association with harmony and the ability to see both sides of a situation, promoting a balanced perspective.
Metaphysically, Alexandrite is often linked to the concept of joy and optimism. Its dramatic shift from a somber green to a vibrant red is interpreted as a symbol of moving from a state of contemplation or melancholy to one of joy and vitality. Some believe the stone can alleviate stress and anxiety, encouraging a more positive outlook on life. It is also associated with creativity and the stimulation of the imagination, thought to help the wearer connect with their inner muse and express themselves more freely.
In modern crystal healing practices, Alexandrite is sometimes used to support the body's natural healing processes and to balance the energies of the heart and mind. Its connection to the name Alexandra, which means "defender of mankind," adds a layer of symbolism related to protection and strength. The stone's rarity and its historical ties to Imperial power contribute to its reputation as a gemstone of abundance and good fortune, making it a popular choice for jewelry intended as a meaningful gift or a personal talisman.
