History and Lore
Ruby has been one of the most admired gemstones in human history. Ancient civilizations, including the Greeks, Romans, and Indians, all regarded ruby with deep reverence. The Greeks believed that ruby was a gift from the gods, and its red color symbolized the lifeblood of the universe. The Romans, on the other hand, associated ruby with the planet Mars, which was considered a symbol of war and strength. In ancient India, ruby was known as the "King of Precious Stones" and was believed to bring prosperity, success, and protection to its wearer.
The use of ruby in jewelry dates back thousands of years. One of the earliest recorded mentions of ruby is in the 15th-century Book of Stones, which described it as a stone that "shines like a flame." Throughout the Middle Ages, ruby was highly prized by European royalty and nobility. It was often set into crowns, scepters, and other symbols of power, reinforcing its association with leadership and authority. In many cultures, ruby was also used as a talisman for protection, believed to ward off evil spirits and negative energies.
By the 19th century, ruby had become a popular gemstone in jewelry design, particularly in pieces meant to celebrate love and commitment. Its deep red color made it a natural symbol of romantic love, and it was often used in engagement rings and other sentimental jewelry. Today, ruby remains a popular choice for those seeking a gemstone that combines beauty, history, and meaning.
In addition to ruby, carnelian and onyx also have rich historical backgrounds. Carnelian has been used since ancient times for its vibrant orange-red color and was particularly favored by the ancient Egyptians, who believed it could enhance vitality and courage. Onyx, with its deep black color and smooth texture, has been used in jewelry and carvings for centuries and is often associated with strength, stability, and grounding. Together, these stones contribute to the rich tapestry of July’s birthstone tradition.
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 caused by the presence of trace amounts of chromium, which replaces some of the aluminum atoms in the crystal structure. In some cases, iron may also play a role in determining the color. Ruby is typically found in metamorphic rocks, particularly in regions where igneous and sedimentary rocks have been subjected to high temperatures and pressures over long periods of time.
The most famous sources of ruby are in Southeast Asia, particularly in Myanmar (formerly Burma), which is known for producing some of the finest rubies in the world. Other notable sources include Thailand, Sri Lanka, Vietnam, and Afghanistan. These regions have a long history of ruby mining and trade, with many of their ruby deposits being discovered and exploited over centuries.
Ruby is formed under specific geological conditions that involve the interaction of molten rock and mineral-rich fluids. The process begins deep within the Earth's crust, where magma cools and solidifies, forming igneous rocks. Over time, these rocks are exposed to heat, pressure, and chemical changes, which can cause them to transform into metamorphic rocks. It is within these metamorphic rocks that ruby crystals can form, often in association with other minerals such as zircon, sillimanite, and mica.
In addition to ruby, carnelian and onyx are also formed through geological processes. Carnelian is a type of chalcedony, a microcrystalline variety of quartz. It is typically formed when silica-rich fluids fill cavities in rocks and cool over time, resulting in the formation of colorful gemstones. Carnelian is commonly found in regions such as Brazil, India, and the United States.
Onyx, on the other hand, is a type of banded agate that is composed of layers of chalcedony and quartz. It is formed in volcanic rock formations, where silica-rich solutions deposit layers of minerals in a regular pattern. Onyx is often found in countries such as Brazil, India, and the United States, and it has been used for centuries in jewelry and decorative objects.
The formation and distribution of these gemstones highlight the natural beauty and diversity of the Earth's geological processes. Their rarity and quality are influenced by a variety of factors, including the specific conditions under which they form, the purity of their chemical composition, and the clarity of their crystal structure.
Gemological Properties
Ruby is one of the hardest gemstones, with a Mohs hardness rating of 9. This high level of hardness makes it resistant to scratches and abrasions, which is important for a gemstone that is often used in jewelry. Despite its hardness, ruby is also known for its toughness, or resistance to breakage or chipping. However, ruby can have internal fractures or inclusions that may affect its durability. These inclusions are often visible under magnification and can vary in size and shape, from small pinpoints to larger, more noticeable features.
In terms of clarity, ruby is evaluated based on the presence and visibility of inclusions. Some inclusions are considered natural and can even enhance the value of a ruby by proving its authenticity. However, large or visible inclusions can reduce the clarity and overall appeal of a stone. The most valuable rubies are those that are free of inclusions or have only minor, barely visible inclusions.
The color of ruby is one of its most defining characteristics. The most desirable color is a deep, vivid red with a slight bluish or purplish secondary tone. This color is often referred to as "pigeon's blood" and is considered the highest quality ruby. The intensity and purity of the color are influenced by the concentration of chromium and the presence of other trace elements.
In addition to ruby, carnelian and onyx also have distinct gemological properties. Carnelian is a translucent to opaque gemstone with a hardness of 6.5 to 7 on the Mohs scale. It is often cut into cabochons or beads and is known for its warm, orange-red color. Onyx, with a hardness of 6.5 to 7, is typically opaque and is often cut into flat, smooth stones that can be carved or engraved. Its deep black color and smooth texture make it a popular choice for rings, bracelets, and pendants.
Understanding the gemological properties of these stones is essential for selecting and caring for July birthstone jewelry. Each gemstone has its own unique characteristics that affect its appearance, durability, and suitability for different types of jewelry.
Symbolism and Metaphysical Beliefs
Throughout history, ruby has been associated with a wide range of symbolic meanings and metaphysical properties. In many cultures, it has been regarded as a stone of power, protection, and vitality. The deep red color of ruby is often linked to the heart, making it a symbol of love, passion, and life force. In ancient India, ruby was believed to bring prosperity and success to its wearer, while in ancient China, it was associated with good fortune and longevity.
Ruby is also believed to have protective properties. Many cultures have used it as a talisman to ward off evil spirits, negative energies, and misfortune. In some traditions, ruby was worn as a protective charm during battle or other dangerous situations, as it was believed to bring courage and strength to the wearer. In modern times, ruby is still valued for its protective and energizing properties, making it a popular choice for those seeking to enhance their vitality and confidence.
Carnelian and onyx also carry their own unique symbolic meanings and metaphysical properties. Carnelian is often associated with courage, creativity, and motivation. It is believed to help individuals overcome fear, take action, and pursue their goals with confidence. Onyx is associated with strength, stability, and grounding. It is believed to help individuals remain centered, focused, and emotionally balanced, especially during times of stress or uncertainty.
These stones, when worn or used in meditation and healing practices, are thought to enhance personal energy and well-being. They are often used in crystal healing, where they are placed on or near the body to promote physical, emotional, and spiritual healing. The combination of ruby, carnelian, and onyx makes for a powerful July birthstone tradition, offering a diverse range of energies and benefits to those born during this month.
Care and Cleaning
Proper care is essential for preserving the beauty and value of ruby and other July birthstones. Due to its high hardness and durability, ruby is relatively easy to care for, but it still requires some attention to maintain its brilliance. Ruby should be cleaned with warm, soapy water and a soft cloth or brush. Ultrasonic and steam cleaners can also be used, but it is important to ensure that the ruby does not have any fractures or inclusions that could be damaged by these methods.
Carnelian and onyx require a bit more care due to their lower hardness and susceptibility to scratches and abrasions. Carnelian should be cleaned with a soft cloth and warm, soapy water, and it should be kept away from harsh chemicals or abrasive materials. Onyx, with its deep black color and smooth texture, can also be cleaned with a soft cloth and warm, soapy water. It should be stored separately from harder gemstones to avoid scratches.
When storing July birthstone jewelry, it is important to keep each piece in a separate compartment or pouch to prevent damage. Ruby, carnelian, and onyx should be stored in a cool, dry place to avoid exposure to extreme temperatures and humidity, which can affect their appearance and durability.
By following these care and cleaning guidelines, the beauty and value of July birthstones can be preserved for many years to come. Proper care ensures that these gemstones remain as vibrant and meaningful as the day they were first worn.
