The ruby, the official birthstone for July, is a gemstone that embodies the fiery spirit of the month in which it is born. Renowned for its deep red hue and symbolic associations with love, vitality, and protection, ruby has captivated cultures for centuries. As the hardest gemstone after diamond, it is not only a symbol of enduring beauty but also one of strength and resilience. This article delves into the historical, geological, and metaphysical dimensions of the ruby, exploring its significance as a birthstone and its enduring appeal in jewelry and culture.
Introduction
The ruby, often referred to as the "King of Gemstones," is the primary birthstone for those born in July. It is celebrated for its rich red color, which is attributed to trace amounts of chromium within the corundum crystal structure. Beyond its visual allure, ruby carries deep symbolic meaning, representing love, power, and protection. It has been a favored gemstone in royal and historical contexts, often associated with divine favor and invincibility. This article explores the ruby’s geological properties, historical significance, metaphysical beliefs, and practical care tips. By examining these facets, we gain a comprehensive understanding of why the ruby remains a cherished gemstone and a meaningful choice for those born in July.
History and Lore
The ruby has a long and storied history, with its use dating back to ancient civilizations. In ancient India, ruby was revered as the "king of precious stones" due to its rarity, hardness, and beauty. Indian jewelers and scholars considered it a symbol of life force and youthful energy. Some historical accounts suggest that ruby was believed to possess mystical powers, including the ability to predict misfortune or danger and to cure inflammatory diseases. These beliefs were often tied to the ruby's association with the life force, represented by the color of blood.
In medieval Europe, ruby was also held in high esteem. It was believed that the gemstone could bring protection and power to its wearer. Burmese warriors, for instance, were said to wear ruby to make them invincible in battle. The stone’s fiery red color was thought to imbue the wearer with courage and strength. During the Renaissance, ruby was often featured in royal regalia and crowns, symbolizing divine right and power.
The ruby's status as the July birthstone was not always fixed. Before 1912, when the Jewelers of America officially adopted ruby as the July birthstone, both onyx and turquoise were considered appropriate gemstones for this month. This shift reflects the evolving standards and practices within the gemstone trade and the growing recognition of ruby's unique qualities and cultural significance.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The deep red color of ruby is due to trace amounts of the element chromium. The more chromium present in the crystal structure, the more intense the red color becomes. The finest rubies are known for their "pigeon's blood" color, a deep red with a slight purple hue that is highly prized in the gem trade.
Corundum forms under high-pressure and high-temperature conditions deep within the Earth's crust. It is typically found in metamorphic rocks, such as marble and schist, which form when sedimentary or igneous rocks are subjected to intense heat and pressure. Over millions of years, the presence of chromium in these environments leads to the formation of ruby crystals.
The most significant sources of ruby include:
Myanmar (Burma): Historically, Myanmar has been the most renowned source of high-quality rubies. The Mogok region, in particular, is famous for producing the finest "pigeon's blood" rubies. These stones are often considered the benchmark for ruby quality.
India and Sri Lanka: These regions have a long history of ruby mining and have produced many notable gemstones. Sri Lankan rubies are known for their vibrant red color and clarity.
Thailand and Cambodia: These countries have also been significant sources of ruby, although the quality can vary. Thai rubies, in particular, have been historically treated to enhance their color and clarity.
Madagascar and Tanzania: More recently, these African countries have emerged as new sources of ruby. While they may not yet produce stones of the same quality as those from Myanmar, they contribute to the global supply of ruby.
Rubies are typically found in alluvial deposits, where they have been eroded from their original rock formations and transported by water. These alluvial deposits make ruby mining a labor-intensive process, as the gemstones are often found in riverbeds and other sedimentary environments.
Gemological Properties
Ruby is one of the most durable gemstones, second only to diamond in terms of hardness on the Mohs scale. It scores a 9 on this scale, which means it is highly resistant to scratches and wear. This durability makes ruby an excellent choice for everyday jewelry, as it can withstand the rigors of regular use without losing its luster or structural integrity.
The chemical composition of ruby is aluminum oxide (Al₂O₃), with the red coloration caused by chromium impurities. The presence of these impurities can vary, leading to differences in color and clarity among ruby specimens. The most valuable rubies are those with a deep, rich red color and minimal inclusions. Inclusions, which are internal flaws or imperfections, can affect the clarity and appearance of the gemstone. However, some inclusions are natural and can be used to identify genuine rubies.
Ruby can be cut into a variety of shapes and styles, depending on the desired aesthetic and the characteristics of the rough stone. Common cuts include the round brilliant cut, which is designed to maximize the gemstone's brilliance and fire, and the step cut, which emphasizes the ruby's color and clarity. Other cuts, such as the cushion cut and the emerald cut, are also used to showcase the ruby's unique qualities.
The refractive index of ruby is between 1.76 and 1.78, which means it bends light in a way that enhances its brilliance and color. This optical property, combined with the gemstone's high hardness, makes ruby a desirable choice for jewelry that requires both durability and visual appeal.
Symbolism and Metaphysical Beliefs
The ruby has long been associated with a range of symbolic meanings and metaphysical properties. In many cultures, it is seen as a stone of passion, love, and vitality. These associations stem from its deep red color, which is often linked to the life force and energy. In ancient India, ruby was considered a symbol of power and youthful energy, and it was believed to bring protection and strength to the wearer.
In medieval Europe, ruby was associated with divine favor and invincibility. It was often used in royal regalia and crowns, where it symbolized the power and authority of the monarch. The belief that ruby could imbue the wearer with courage and strength was particularly strong among warriors and leaders.
Modern metaphysical traditions continue to attribute significant meaning to ruby. It is often associated with the heart chakra, which is believed to be the center of love, compassion, and emotional balance. Wearing ruby is thought to enhance one's ability to express love and to attract positive energy and relationships. It is also believed to promote vitality and motivation, making it a popular choice for those seeking to boost their energy and drive.
In addition to its associations with love and vitality, ruby is also believed to offer protection. Some sources suggest that it can shield the wearer from negative energies and promote a sense of security and confidence. This protective quality makes ruby a valuable stone for those who feel the need for additional support and strength in their lives.
Care and Cleaning
Due to its high hardness and durability, ruby is a relatively low-maintenance gemstone that can be worn and cared for with minimal effort. However, proper care is essential to ensure that the gemstone retains its beauty and longevity.
One of the most important aspects of ruby care is avoiding exposure to harsh chemicals. While ruby is resistant to scratches and wear, it can be damaged by exposure to acidic or abrasive substances. It is advisable to remove ruby jewelry before using household cleaners, swimming in chlorinated water, or engaging in activities that involve contact with harsh chemicals.
Cleaning ruby is a straightforward process. A simple solution of mild soap and warm water is typically sufficient to remove dirt and debris. The gemstone can be gently scrubbed with a soft brush and then rinsed thoroughly with clean water. After cleaning, it should be dried with a soft cloth to prevent water spots.
It is also important to store ruby jewelry properly to prevent damage. Rubies should be kept separate from other gemstones to avoid scratches, as even the hardest gemstones can be affected by abrasion over time. A soft, lined jewelry box or a cloth pouch is an ideal storage solution for ruby jewelry.
When it comes to professional care, it is advisable to have ruby jewelry inspected and cleaned by a qualified jeweler at least once a year. This can help identify any potential issues, such as loose settings or wear, and ensure that the gemstone remains in excellent condition.
