Alexandrite stands as a particularly captivating gemstone, recognized as one of three official birthstones for the month of June, alongside pearl and moonstone. Its allure stems not only from its rarity but also from its remarkable ability to change color depending on the light source – exhibiting a bluish-green hue in daylight and transforming to a reddish-purple under incandescent light. This unique characteristic has cemented its place as a treasured gem for jewelry and a meaningful symbol for those born in June. This article will delve into the history, geological origins, gemological properties, symbolism, and care of this extraordinary stone, drawing solely from available sources.
History and Lore
The story of Alexandrite begins in the 1830s with its discovery in the Ural Mountains of Russia. This initial find quickly established the gem’s reputation, and it was named in honor of Prince Alexander II of Russia, to whom the stone was presented on his coming of age. The gem quickly became popular amongst the Russian aristocracy due to its patriotic colors – red and green mirroring the colors of the Imperial Russian flag when viewed under different lighting conditions.
While the original Russian source is historically significant, Alexandrite is now also found in Brazil, Sri Lanka, and East Africa. Notably, the most vibrant color-changing Alexandrite currently comes from a single mine in Central Brazil, contributing to its continued rarity and value. Despite the availability of alternative birthstones for June – pearls and moonstone – Alexandrite is often favored for its exceptional beauty and unique optical phenomenon. It is considered a gift that will be admired and remembered.
Geological Formation and Sources
Alexandrite is a variety of the mineral chrysoberyl. Its formation requires a unique geological environment rich in beryllium and chromium. These elements rarely occur together, contributing to the gem’s scarcity. The Ural Mountains in Russia were the first location where this specific combination was found, leading to the initial discovery of Alexandrite.
Today, significant sources include Brazil, particularly a single mine in the central region known for producing stones with exceptional color change. Alexandrite is also found in Sri Lanka and East Africa, though the quality and intensity of the color change can vary between these locations. The origin of the gem can provide insight into its value and rarity, with Russian and Brazilian Alexandrite generally commanding higher prices.
Gemological Properties
Alexandrite possesses a compelling set of gemological properties that contribute to its desirability. Its hardness registers at 8.5 on the Mohs scale, making it a durable gemstone suitable for all types of jewelry, including rings intended for everyday wear. This durability ensures resistance to scratches and maintains its brilliance over time.
The most defining characteristic of Alexandrite is its color change. This phenomenon is due to its ability to absorb different wavelengths of light depending on the source. In daylight or fluorescent light, it typically appears bluish-green. However, under incandescent light, such as candlelight, it shifts to a reddish-purple hue. The clarity of Alexandrite can vary, with inclusions being common in natural stones. Stones with fewer visible inclusions are considered more valuable, enhancing their brilliance and overall appeal.
A typical Alexandrite used in jewelry measures 8x6.5mm, as seen in some necklace pendants. It is often set in sterling silver, sometimes with an 18K gold finish, and can be found in a variety of jewelry styles, including rings, necklaces, earrings, and bracelets.
Here's a table summarizing key gemological properties:

Symbolism and Metaphysical Beliefs
Alexandrite is rich in symbolic meaning, particularly for those born in June. It is associated with balance, intuition, and renewal. The gem’s dual colors are often interpreted as representing harmony between opposites, making it a meaningful stone for individuals seeking personal growth and equilibrium. Its connection to renewal also symbolizes hope and transformation.
The color-changing nature of Alexandrite is also seen as a metaphor for adaptability and the ability to navigate life’s changes with grace. It is believed to foster self-esteem and encourage a positive outlook.
Care and Cleaning
Maintaining the beauty of Alexandrite jewelry requires careful attention. Regular cleaning with warm, soapy water and a soft brush is recommended to remove dirt and oils. Harsh chemicals and ultrasonic cleaners should be avoided, as they may damage the stone.
Due to its hardness, Alexandrite is relatively resistant to scratches, but it can still chip or crack if subjected to hard impacts. It is advisable to remove Alexandrite jewelry during rigorous activities to prevent damage. Proper storage is also crucial; keeping Alexandrite separate from other jewelry in a soft cloth or padded jewelry box will help prevent scratches and maintain its brilliance.
Alexandrite in Jewelry
Alexandrite’s versatility makes it a popular choice for various jewelry settings. Rings featuring Alexandrite are particularly trendy due to their visual impact and durability. Necklaces, earrings, and bracelets also showcase the gem’s unique color-changing property beautifully. The stone is often set in sterling silver, sometimes finished with gold, to complement its vibrant hues.
Modern jewelry designs often incorporate Alexandrite with other gemstones or diamonds to enhance its brilliance and create stunning pieces. The North Star Alexandrite necklace, for example, combines a CZ Alexandrite with diamond accents, creating a celestial-inspired design.
