By exploring these facets of ruby, we aim to provide a thorough understanding of why this gemstone remains a treasured possession for many.
History and Lore
Ruby has a long and storied history, with its use and reverence dating back to ancient civilizations. In Sanskrit, ruby is referred to as Ratnaraj, meaning “king of gemstones,” a title that reflects its esteemed status. Ancient cultures across the world have recognized the ruby’s powerful symbolism and believed in its protective and prosperous properties. From the courts of India and China to the palaces of medieval Europe, ruby has been a gemstone of choice for royalty and the elite.
In ancient times, ruby was believed to bring prosperity, ward off evil, and ensure victory in battle. It was often carried by warriors for protection and was embedded in royal regalia to signify power and divine favor. The ruby’s vibrant red color, caused by the presence of chromium, has long been associated with blood, fire, and passion, making it a symbol of life force and vitality. These associations have persisted through the centuries, contributing to ruby’s enduring appeal.
The designation of ruby as the July birthstone is a more recent development. 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. The choice of ruby as the primary birthstone for July reflects its historical significance, durability, and symbolic value. Today, ruby remains a popular and meaningful choice for those born on July 1st.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, a crystalline form of aluminum oxide (Al₂O₃). The red color of ruby is due to the presence of trace amounts of chromium within the crystal structure. This element replaces some of the aluminum ions in the lattice, causing the characteristic red hue. The intensity of the color can vary depending on the concentration of chromium and other factors such as the crystal’s structure and inclusions.
Corundum, which includes both ruby and sapphire, is formed under intense heat and pressure deep within the Earth’s crust. The formation of ruby typically occurs in metamorphic rocks such as marble and in igneous rocks such as basalt. These geological conditions are found in specific regions around the world, where ruby deposits have been historically mined.
Notable sources of ruby include:
- Myanmar (Burma): Known for producing some of the finest and most valuable rubies, particularly those with a deep red to purplish-red color.
- Thailand: A major center for ruby trade and treatment, Thailand has been a key player in the ruby market for centuries.
- Sri Lanka: Known for producing high-quality rubies with a vibrant red color, Sri Lanka is a significant source of ruby.
- Madagascar: In recent decades, Madagascar has emerged as a new and important source of ruby, with high-quality stones being discovered.
- India, Vietnam, and Tanzania: These countries also have ruby deposits and contribute to the global ruby market.
The process of mining ruby can be challenging, as the gemstone is often found in remote and difficult-to-reach areas. Mining techniques vary from traditional hand-digging to more modern methods involving heavy machinery. Once extracted, ruby rough is cut and polished to enhance its color and clarity, making it suitable for jewelry and other applications.
Gemological Properties
Ruby is one of the most valuable and durable gemstones in the world. Its properties are essential for understanding its appeal and practical use in jewelry. Below is a detailed overview of ruby’s gemological properties:
- Chemical Formula: Al₂O₃ (aluminum oxide)
- Hardness: 9 on the Mohs Hardness Scale
- Refractive Index: 1.76–1.78
- Color: Deep red, often described as “pigeon’s blood” when the color is at its most intense
- Luster: Vitreous (glassy)
- Transparency: Transparent to translucent
- Specific Gravity: 4.00–4.10
- Crystal System: Hexagonal
- Cleavage: Poor to none
- Inclusions: Common; may include rutile needles, other mineral inclusions, and growth zoning
The hardness of ruby, second only to diamond on the Mohs scale, makes it highly resistant to scratches and suitable for everyday wear in jewelry. Its refractive index contributes to its brilliance and fire, enhancing its visual appeal. The deep red color of ruby, often referred to as “pigeon’s blood,” is one of the most desirable and valuable characteristics of the gemstone. This term is used to describe rubies with a vibrant red hue and a slight blue secondary hue that gives them a lively appearance.
Ruby is typically cut into various shapes, including round, oval, cushion, and emerald cuts. The choice of cut depends on the shape and quality of the rough stone, as well as the desired aesthetic outcome. High-quality rubies are often faceted to maximize their color and brilliance, while lower-quality stones may be cut to reduce the visibility of inclusions.
The presence of inclusions in ruby is not uncommon and can be used to identify the gemstone. These inclusions, which may include rutile needles or other mineral deposits, are often referred to as “silk” and can contribute to the gemstone’s character and value. In some cases, inclusions are so fine that they appear as a hazy, milky effect, which is known as “star ruby.”
Symbolism and Metaphysical Beliefs
Ruby has been associated with various symbolic meanings and metaphysical properties across different cultures and eras. Its vibrant red color, which is often linked to the heart, has made it a symbol of love, passion, and vitality. In many traditions, ruby is believed to bring good fortune, protection, and emotional strength to its wearer.
In ancient times, ruby was considered a stone of power and was often used in royal regalia to signify authority and divine favor. It was believed to protect the wearer from harm and bring victory in battle. In some cultures, ruby was also associated with the sun and was thought to carry the energy and warmth of the sun’s rays. This connection to the sun contributed to its symbolism of vitality and life force.
In modern times, ruby continues to be associated with these symbolic meanings. It is often given as a gift to celebrate love and passion, making it a popular choice for engagement rings and other romantic jewelry. Ruby is also believed to stimulate the heart chakra and promote emotional balance and courage. Some practitioners of crystal healing use ruby to enhance energy levels, improve circulation, and encourage a sense of inner strength.
Ruby is also considered a protective stone, believed to guard the wearer from negative influences and promote a sense of security. It is often worn as a talisman or carried as a personal charm to bring good luck and ward off misfortune. In some traditions, ruby is also associated with prosperity and success, making it a popular choice for those seeking financial and career advancement.
While these metaphysical beliefs are not scientifically proven, they reflect the cultural and historical significance of ruby. Whether worn for its symbolic meaning or its aesthetic appeal, ruby remains a cherished gemstone with a rich and enduring legacy.
Care and Cleaning
Given its high hardness and durability, ruby is well-suited for everyday wear in jewelry. However, like all gemstones, it requires proper care to maintain its beauty and longevity. Here are some key guidelines for cleaning and maintaining ruby jewelry:
- Cleaning: Ruby can be cleaned with warm, soapy water and a soft brush. Avoid using harsh chemicals or abrasive cleaners, as they can damage the gemstone or its setting. Ultrasonic cleaners can be used for ruby, but it is important to check with a professional jeweler to ensure that the gemstone and setting are suitable for this method.
- Storing: Store ruby jewelry separately from other gemstones to prevent scratches. A soft cloth or jewelry box with individual compartments is recommended.
- Wearing: Ruby is durable enough for daily wear, but it is still a good idea to avoid exposing it to extreme conditions such as high heat, prolonged sunlight, or harsh chemicals. These factors can potentially affect the gemstone’s color and clarity over time.
- Professional Maintenance: It is advisable to have ruby jewelry inspected and cleaned by a professional jeweler on a regular basis. This can help identify any potential issues such as loose settings or wear on the gemstone.
By following these care guidelines, ruby jewelry can be enjoyed for generations, preserving its beauty and value.
