Introduction
Spinels are a relatively recent addition to the list of August birthstones, though their history dates back centuries. Traditionally, peridot and sardonyx were the primary birthstones for August, but the growing popularity of spinel has led to its recognition as an alternative. This gemstone's versatility, both in terms of color and hardness, makes it a valuable addition to any jewelry collection. From deep reds to vibrant pinks and even rare blues, spinels offer a spectrum of colors that appeal to a wide range of tastes.
This article will explore the history of spinels, their geological formation, gemological properties, cultural symbolism, and how to care for them. Additionally, it will highlight the reasons why spinels have become a popular choice among jewelry designers and collectors.
History and Lore
Spinels have a rich and storied history, often mistaken for rubies due to their similar appearance. The gemstone has been known to adorn the crowns and jewelry of royalty for centuries. One of the most famous examples is the "Balas Ruby," a term historically used to describe large red spinels that were imported from the region of Badakhshan in Afghanistan. These spinels were so prized that they were often used in royal regalia, including the Crown Jewels of the United Kingdom and the Crown of the Netherlands.
In medieval times, spinels were believed to possess protective and healing properties. They were thought to bring courage, enhance communication, and promote stability. These beliefs have persisted into modern times, with many people still attributing metaphysical benefits to spinels. The gemstone's vibrant colors and durability have made it a favorite among jewelers and collectors, especially those looking for a more affordable alternative to rubies.
Geological Formation and Sources
Spinels are formed under high-pressure conditions deep within the Earth's crust and mantle. They are typically found in igneous rocks, such as basalt and gabbro, and are often brought to the surface through volcanic activity. The unique conditions required for spinel formation contribute to their rarity and the variety of colors they can exhibit.
The primary sources of spinels include Afghanistan, Pakistan, Sri Lanka, Burma (Myanmar), and Madagascar. Each of these locations produces spinels with distinct characteristics. For example, Afghan spinels are known for their deep red color, while those from Sri Lanka can range from pink to orange. The geological diversity of these regions has resulted in a wide range of spinel colors, making them highly sought after in the gemstone market.
Spinels are also found in meteorites, which adds to their mystique and allure. The fact that some spinels have origins beyond our planet makes them even more fascinating to gemologists and collectors. The presence of spinels in meteorites underscores their extraterrestrial nature and provides a unique perspective on their formation and rarity.
Gemological Properties
Spinels are known for their exceptional hardness and durability, which makes them suitable for use in a variety of jewelry pieces, including rings, pendants, and earrings. On the Mohs scale of mineral hardness, spinels typically range from 7.5 to 8, which is slightly less than rubies and sapphires but still quite durable. This hardness ensures that spinels can withstand daily wear and tear, making them an excellent choice for everyday jewelry.
The refractive index of spinels is relatively high, which contributes to their brilliance and fire. This property, combined with their rich colors, gives spinels a vibrant and lively appearance. The most valuable spinels are those with a deep red or pink color, as these are the most similar to rubies and are highly sought after in the market.
In terms of clarity, spinels can vary from eye-clean to slightly included. However, most spinels with good clarity are available in sizes suitable for jewelry. The presence of inclusions does not significantly detract from the beauty of spinels, as they are often hidden by the gemstone's high refractive index.
Spinels are also known for their pleochroism, which means they can display different colors when viewed from different angles. This characteristic adds to their visual appeal and makes each spinel unique. The pleochroism in spinels is particularly noticeable in the red and pink varieties, where the color can shift from red to brown or even to a more orange hue depending on the angle of light.
Symbolism and Metaphysical Beliefs
Spinels have been attributed with various symbolic meanings and metaphysical properties across different cultures and eras. In ancient times, spinels were believed to bring courage, enhance communication, and promote stability. These beliefs have persisted into modern times, with many people still attributing protective and healing properties to spinels.
In the realm of metaphysical beliefs, spinels are associated with the root chakra, which is responsible for grounding and stability. This connection makes spinels a popular choice for those seeking to enhance their sense of security and confidence. Additionally, spinels are believed to help with stress relief, making them a valuable tool for those dealing with anxiety or emotional challenges.
The vibrant colors of spinels are also thought to have different meanings. For example, red spinels are associated with passion and energy, while pink spinels are believed to promote love and compassion. These color-based associations have led to the use of spinels in various forms of jewelry and decorative objects, where their colors can be harnessed for their symbolic meanings.
In modern gemology, the use of spinels in jewelry is often linked to their versatility and affordability. Designers and collectors appreciate the ability to find spinels in a wide range of colors, making them a valuable addition to any collection. The combination of their beauty, durability, and symbolic meanings has contributed to their growing popularity in the gemstone market.
Care and Cleaning
Proper care and cleaning are essential for maintaining the beauty and longevity of spinels. Due to their high hardness and durability, spinels can be cleaned using standard jewelry cleaning methods. However, it is important to avoid using harsh chemicals or ultrasonic cleaners, as these can potentially damage the gemstone or its setting.
For routine cleaning, a soft cloth and mild soap and water solution are recommended. Gently polish the spinel with the cloth to remove any dirt or residue. It is also advisable to store spinels separately from other gemstones to prevent scratches, especially when stored with softer stones like pearls or opals.
When handling spinels, it is important to be gentle, as they can be susceptible to chipping if subjected to impact. Avoid wearing spinel jewelry during activities that may expose it to physical stress, such as sports or heavy manual labor. By following these simple care guidelines, spinels can be enjoyed for many years to come.
