History and Lore
The history of alexandrite is as rich and intriguing as the gemstone itself. Discovered in the Ural Mountains of Russia in the early 19th century, alexandrite was named after Tsar Alexander II, who was celebrating his 16th birthday at the time of the discovery. The gemstone quickly became a symbol of Russian nobility and was used extensively in royal jewelry and regalia.
The discovery of alexandrite was not merely a scientific event but a cultural one. The gemstone’s color-changing property was considered a natural wonder and was attributed to divine intervention. In the 19th century, alexandrite was believed to possess mystical properties, including the ability to enhance one's intuition and bring good fortune. These beliefs contributed to its popularity among the aristocracy and its eventual integration into the birthstone tradition.
Despite its early fame, alexandrite remained a relatively obscure gemstone for much of the 20th century due to its rarity. However, the discovery of new deposits in Brazil in the 1980s and 1990s significantly increased its availability, allowing it to gain wider recognition and appreciation in the global jewelry market. Today, alexandrite is not only a symbol of Russian heritage but a celebrated birthstone with a growing international following.
Geological Formation and Sources
Alexandrite is a rare and precious gemstone that forms under specific geological conditions. It is a variety of the mineral chrysoberyl, which is composed of beryllium aluminum oxide (BeAl₂O₄). The color-changing property of alexandrite is due to the presence of trace amounts of chromium, which replaces some of the aluminum in the crystal lattice. This substitution creates a unique absorption spectrum that allows the gemstone to absorb and reflect different wavelengths of light depending on the light source.
The formation of alexandrite typically occurs in metamorphic rocks, where high pressure and temperature conditions facilitate the crystallization of chrysoberyl. The presence of chromium is crucial for the development of the color-changing effect, and the concentration of this element determines the intensity of the color change. Alexandrite is primarily found in regions with a history of geological activity, such as the Ural Mountains in Russia, where it was first discovered, and in Brazil, where significant deposits have been found in the states of Minas Gerais and Bahia.
The rarity of alexandrite is further compounded by the difficulty in finding gem-quality crystals. The gemstone is often found in small quantities and is highly susceptible to fractures and inclusions. As a result, only a small percentage of raw alexandrite crystals can be cut into high-quality gemstones suitable for jewelry. This scarcity contributes to the gemstone's high value and desirability.
Gemological Properties
Alexandrite is distinguished by a set of unique gemological properties that set it apart from other gemstones. Its most notable characteristic is its color-changing ability, which is a result of the presence of chromium in the crystal structure. This property, known as the alexandrite effect, allows the gemstone to appear green in daylight and red under incandescent light. The intensity of the color change varies depending on the concentration of chromium and the quality of the crystal.
In terms of hardness, alexandrite ranks between 8.5 and 9 on the Mohs scale, making it one of the hardest gemstones. This high hardness makes it durable and suitable for everyday wear, although it is still susceptible to scratches from materials with a higher hardness, such as diamonds. The gemstone also has a refractive index of approximately 1.74 to 1.78, which contributes to its brilliance and fire when cut and polished.
Alexandrite is typically cut into various shapes, including oval, round, cushion, and emerald cuts, each of which enhances the gemstone's natural beauty and color-changing effect. The choice of cut is often influenced by the shape and clarity of the raw crystal, as well as the desired aesthetic outcome. The gemstone's clarity can vary from eye-clean to slightly included, with the most valuable specimens being those with minimal inclusions and a strong color change.
The carat weight of alexandrite is another important factor in its value and appeal. High-quality alexandrite gemstones are relatively small, with most being under 2 carats. Larger stones are extremely rare and command significantly higher prices in the market. The combination of its rarity, hardness, and unique color-changing properties makes alexandrite a highly sought-after gemstone for collectors and jewelry enthusiasts.
Symbolism and Metaphysical Beliefs
Alexandrite is not only prized for its physical properties but also for the rich symbolism and metaphysical beliefs associated with it. In many cultures, the gemstone is seen as a symbol of balance and harmony, reflecting its ability to change color in different lighting conditions. This duality is often interpreted as a representation of the balance between opposites, such as day and night, light and shadow, or joy and sorrow.
In the realm of metaphysical beliefs, alexandrite is thought to enhance intuition and psychic abilities. It is believed to help individuals connect with their inner wisdom and navigate through life's challenges with clarity and confidence. The gemstone is also associated with protection, particularly from negative energies and emotions. Many people carry alexandrite as a talisman to ward off negativity and promote a sense of calm and stability.
Alexandrite is often used in meditation and healing practices. It is said to stimulate the heart chakra and promote emotional healing, making it a valuable tool for those seeking to overcome past traumas and foster a deeper connection with others. The gemstone is also believed to support the digestive system and improve overall well-being, making it a popular choice in holistic health practices.
As a birthstone, alexandrite is thought to bring good fortune and prosperity to those born in June. It is believed to enhance one's ability to make sound decisions and to provide a sense of direction and purpose in life. These beliefs have contributed to the gemstone's popularity as a meaningful and symbolic choice for engagement rings and other significant jewelry pieces.
Care and Cleaning
Due to its unique properties and relative rarity, proper care and cleaning of alexandrite jewelry are essential to preserving its beauty and value. The gemstone's hardness of 8.5 to 9 on the Mohs scale makes it durable enough for everyday wear, but it is still susceptible to damage from harsh chemicals and physical impacts.
To clean alexandrite jewelry, it is recommended to use a mild detergent and warm water. A soft cloth or a jewelry brush can be used to gently remove any dirt or debris. It is important to avoid using ultrasonic cleaners or steam cleaners, as these can cause damage to the gemstone, especially if it has inclusions or fractures. Harsh chemicals, such as bleach or ammonia, should also be avoided, as they can dull the gemstone's luster and affect its color.
When storing alexandrite jewelry, it is best to keep it in a soft cloth or a padded jewelry box to prevent scratches and impacts. If multiple pieces are stored together, they should be separated to avoid any potential damage. It is also advisable to remove alexandrite jewelry before engaging in activities that could expose it to physical stress, such as sports or heavy lifting.
For more detailed care instructions, it is recommended to consult a professional jeweler or gemologist. They can provide personalized advice based on the specific characteristics of the alexandrite gemstone and the type of jewelry it is set in. Regular inspections and professional cleanings can help ensure that alexandrite jewelry remains in pristine condition for years to come.

For example, a solitaire ring highlights the gemstone's natural beauty and color-changing effect, while a halo ring adds extra brilliance and elegance by surrounding the alexandrite with smaller gemstones.
Customization is another important aspect of alexandrite engagement rings. Many jewelers offer bespoke services that allow couples to design their own rings, incorporating elements that are meaningful to them. This can include choosing the shape and size of the alexandrite gemstone, selecting the type of metal for the setting, and adding engravings or other personal touches.
