Alexandrite is a highly prized gemstone celebrated for its remarkable color-changing ability – appearing green in daylight and shifting to reddish-purple under incandescent light. This unique characteristic, coupled with its relative rarity, makes alexandrite a sought-after gem for collectors, jewelry enthusiasts, and those born in June, for whom it serves as a traditional birthstone. This article will explore the history, geological origins, gemological properties, symbolism, and practical considerations for owning and caring for alexandrite rings, drawing exclusively from available sources.
History and Lore
Alexandrite’s discovery is relatively recent compared to many other gemstones. It was first identified in the Ural Mountains of Russia in 1830, and is named after Prince Alexander II of Russia, to whom it was dedicated. The gem quickly gained favor among the Russian aristocracy due to its patriotic colors – green and red mirroring the colors of the Russian flag.
The discovery of alexandrite in Brazil in 1988, near Nova Era in Minas Gerais, added another significant source to the limited supply. Today, alexandrite is also mined in India, though the quality and color change can vary. The gem’s association with June as a birthstone is a more modern tradition, solidifying its place in popular culture and gemological lore.
Geological Formation and Sources
Alexandrite is a variety of the mineral chrysoberyl. Chrysoberyl itself is a beryllium aluminum oxide (BeAl₂O₄). The color change in alexandrite is caused by the presence of chromium ions within the crystal structure. This unique composition is relatively rare, requiring specific geological conditions for formation.
The primary sources for alexandrite, as documented in available materials, include Russia, Brazil, and India. The Brazilian deposits, discovered in 1988, were located in the state of Minas Gerais. The original Russian source in the Ural Mountains remains historically significant, though current production levels are not detailed in the provided sources. The sources emphasize that the gems used in their rings are sourced responsibly from these locations.
Gemological Properties
Alexandrite possesses a number of distinct gemological properties that contribute to its value and desirability. The most notable is its color change, a phenomenon known as the Alexandrite effect. This effect is strongest in stones with a clear and vivid color change between a green or bluish-green in daylight and a red or purplish-red under incandescent light.
The value of alexandrite is significantly impacted by the clarity of the stone, the strength of the color change, and the carat weight. Semi-transparent alexandrite gems, even with a strong color change, have lower values compared to eye-clean stones. The price increases dramatically with both clarity and color change intensity, and also with increasing carat weight. The quality of the cut and faceting also influences the gem’s brilliance and overall value.
While a precise hardness rating isn't provided, alexandrite is a durable gemstone suitable for everyday wear. The sources do not provide specific details on refractive index, specific gravity, or other detailed gemological data.
Here's a summary of key properties based on the provided sources:
| Property | Description |
|---|---|
| Mineral | Chrysoberyl (Beryllium Aluminum Oxide) |
| Color Change | Green in daylight, Red/Purple in incandescent light |
| Clarity | Significantly impacts value; eye-clean preferred |
| Carat Weight | Value increases dramatically with weight |
| Sources | Russia, Brazil, India |
Symbolism and Metaphysical Beliefs
Alexandrite is often associated with transformation, strength, and balanced emotions. It is considered a symbol of good fortune and is frequently chosen to commemorate change, anniversaries, and new beginnings. Its status as the birthstone for June further enhances its symbolic significance for those born in that month. The sources highlight the romantic connotations of the color change, making it a popular choice for engagement and wedding rings.
Alexandrite Rings: Styles and Considerations
Alexandrite rings are available in a variety of styles, catering to diverse tastes. Popular designs include solitaire rings, which showcase the gemstone’s color-changing properties, halo rings that add brilliance with surrounding diamonds, vintage-inspired rings with intricate details, and three-stone rings that incorporate alexandrite alongside other gems.
Rings are commonly set in 14k or 18k gold, both yellow and white gold options are available. The sources emphasize the use of genuine, untreated alexandrite gemstones, distinguishing their offerings from lab-created or treated stones.
When considering an alexandrite ring, it’s important to understand that the price can vary significantly based on the gem’s quality. Factors such as clarity, color change intensity, and carat weight all contribute to the overall cost. The sources suggest that a “Jewelry Store Price” is often a conservative estimate based on current market values for the metal, labor, and the alexandrite itself.
Care and Cleaning
While durable, alexandrite rings require careful handling and cleaning to maintain their brilliance. The sources do not provide specific cleaning instructions, but given its durability, gentle cleaning with warm soapy water and a soft brush is likely appropriate. Avoid harsh chemicals or abrasive cleaners, as these could damage the gemstone or the setting. Regular inspection of the setting is recommended to ensure the alexandrite is securely held.
Conclusion
Alexandrite remains a captivating and valuable gemstone, prized for its unique color-changing ability and relative rarity. From its discovery in the Ural Mountains to its modern status as a June birthstone, alexandrite has captured the imagination of gem enthusiasts and jewelry lovers alike. The gem’s symbolism of transformation and strength, combined with its stunning visual appeal, ensures its continued desirability for generations to come. The availability of alexandrite rings in a variety of styles and settings makes this remarkable gemstone accessible to those seeking a truly special and unforgettable piece of jewelry.
