Introduction
The July birthstone is primarily represented by the ruby, a gemstone whose deep red color has captivated cultures for centuries. While ruby is the official and most recognized birthstone for July, the month also includes secondary and alternative options like onyx, turquoise, and carnelian. These stones offer a range of colors and meanings, making July a month rich in symbolic and aesthetic diversity. This article delves into the gemological properties of ruby, its historical and cultural importance, and the characteristics of its alternative birthstones. Additionally, it provides guidance on how to care for these gems and how to choose the right stone for jewelry.
History and Lore
The ruby has a storied history that spans continents and centuries. Known as the "king of precious stones" in ancient India, the ruby was revered not only for its beauty but also for its supposed mystical properties. In medieval Europe, it was believed that rubies brought health, wisdom, and success in love. Warriors in Burma wore rubies into battle, believing the stones made them invincible. The deep red color of the ruby was often associated with the life force of blood, symbolizing power, vitality, and youthful energy.
The term "ruby" comes from the Latin word ruber, meaning "red," and this fiery hue has made it a symbol of passion and love. In ancient times, people wore rubies as protection against evil and misfortune. Some believed the gemstone could predict danger or cure inflammatory diseases and soothe anger. These beliefs, though not scientifically validated, reflect the ruby's enduring cultural significance.
While ruby remains the primary birthstone for July, other gemstones have also been historically linked to the month. Onyx, for example, has been used in jewelry and amulets for thousands of years, particularly in ancient Egypt and Greece. Turquoise, with its distinctive blue-green color, was highly valued in the Middle East and the Americas for its protective and healing properties. Carnelian, a warm orange-red stone, was favored in the ancient Near East for its energizing and grounding qualities.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The red color of ruby is due to trace amounts of the element chromium, which replaces some of the aluminum in the crystal structure. The more chromium present, the stronger the red color. The finest quality ruby exhibits a deep red with a hint of purple, a color known in the trade as "pigeon’s blood." This term is most commonly associated with Burmese rubies, which are considered the standard for color and quality.
Ruby is typically found in metamorphic rocks, particularly in limestone and marble. The most famous deposits are in Myanmar (formerly Burma), where the rubies are known for their exceptional color and fluorescence. Other significant sources include Thailand, Sri Lanka, Vietnam, and Kenya. Each of these locations produces rubies with slightly different characteristics, such as color tone and clarity.
Onyx, a type of chalcedony, is a translucent to opaque form of quartz that forms in banded layers. It is typically found in volcanic rocks and is known for its durability and ease of carving. Onyx is primarily mined in Brazil, India, and Mexico.
Turquoise is a hydrated phosphate of aluminum and copper, with the chemical formula Al₂(OH)₃PO₄·4(H₂O). It forms in arid regions where copper-rich minerals are exposed to water. The most famous source of turquoise is the American Southwest, particularly the mines of Arizona and New Mexico. Other notable sources include China, Egypt, and Iran.
Carnelian is a variety of chalcedony that gets its orange-red color from iron impurities. It is formed through the deposition of silica in sedimentary rock, and it is often found in layers with other chalcedony varieties. Carnelian is mined in Brazil, India, and the United States.
Gemological Properties
Ruby is one of the hardest gemstones, ranking 9 on the Mohs scale of mineral hardness. This high hardness makes it durable and suitable for everyday wear in jewelry. Its refractive index ranges from 1.76 to 1.78, and it exhibits strong pleochroism, meaning it can show different colors when viewed from different angles. The most desirable ruby color is a deep red with a slight purplish tone, often referred to as "pigeon’s blood." This color is most commonly found in Burmese rubies and is considered the benchmark for ruby quality.
Rubies can occur in a range of colors, from pinkish red to purplish red and even orangey red. The color variation is due to the presence of different trace elements and the geological conditions in which the ruby formed. The clarity of ruby can vary, with some stones being nearly flawless and others containing inclusions that are characteristic of their origin. These inclusions can be used to identify the source of the ruby, as certain inclusions are unique to specific regions.
Onyx is a relatively hard gemstone, ranking between 6.5 and 7 on the Mohs scale. It is known for its smooth surface and its ability to be cut into intricate shapes. Turquoise has a lower hardness, typically between 5 and 6 on the Mohs scale, which means it requires careful handling to avoid scratches and chips. Carnelian, like onyx, is a type of chalcedony and has a hardness of 6.5 to 7 on the Mohs scale.
The chemical composition of these gemstones plays a significant role in their properties and appearance. Ruby’s hardness and brilliance make it ideal for use in rings, pendants, and other types of jewelry that are worn frequently. Onyx and carnelian, being slightly softer, are often used in more delicate jewelry designs, such as earrings and pendants. Turquoise, with its lower hardness, is best suited for jewelry that is not subjected to constant wear and tear, such as brooches or occasional-use necklaces.
Symbolism and Metaphysical Beliefs
The ruby has long been associated with powerful and positive attributes. In many cultures, it is a symbol of love, passion, and vitality. The deep red color is often linked to the heart and the life force, making it a popular choice for jewelry that represents enduring love and commitment. In ancient times, rubies were believed to have protective properties, warding off evil and bringing good fortune. Some cultures believed that rubies could predict danger or misfortune, and others claimed that the gemstone could cure inflammatory diseases and soothe anger.
Modern metaphysical beliefs also assign positive energies to the ruby. It is considered a stone of motivation, courage, and confidence. Ruby is said to enhance vitality and energy, making it a popular choice for those seeking to boost their physical and emotional strength. It is also associated with the root and heart chakras, helping to ground the wearer and promote a sense of balance and well-being.
Onyx is often regarded as a protective stone, particularly for those who are dealing with stress, anxiety, or emotional instability. It is believed to help absorb negative energies and promote emotional strength and resilience. Onyx is also associated with the root chakra, helping to provide a sense of stability and security.
Turquoise is known for its calming and healing properties. It is often used to promote emotional balance, enhance communication, and provide protection from negative influences. In many Native American cultures, turquoise is considered a sacred stone, representing the sky and the earth. It is believed to bring good fortune and spiritual insight.
Carnelian is associated with energy, creativity, and confidence. It is believed to help stimulate the lower chakras, particularly the root and sacral chakras, promoting a sense of vitality and motivation. Carnelian is also considered a stone of protection, particularly in matters of love and relationships. It is often used to enhance personal power and to encourage bold and decisive action.
Care and Cleaning
Proper care and maintenance are essential for preserving the beauty and longevity of ruby and its alternative birthstones. Ruby is one of the hardest gemstones, making it highly resistant to scratches and wear. However, it is still important to handle it with care to avoid chipping or fracturing, particularly along any inclusions or fractures. To clean a ruby, use a soft cloth and mild soapy water. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the gemstone or any treatments it may have undergone.
Onyx and carnelian are relatively durable gemstones, but they are softer than ruby and require more careful handling. Avoid exposing them to harsh chemicals or abrasive materials, as these can scratch the surface. To clean onyx and carnelian, use a soft cloth and warm, soapy water. Dry them with a lint-free cloth to avoid water spots.
Turquoise is more delicate than ruby, onyx, or carnelian and requires special care. It is sensitive to heat, sunlight, and moisture, which can cause it to fade or become discolored. To clean turquoise, use a soft cloth and a mild detergent. Avoid soaking it in water or using ultrasonic cleaners, as these can damage the stone. Store turquoise jewelry in a cool, dry place to prevent it from drying out or losing its color.
When storing any of these gemstones, it is best to keep them separate to avoid scratches and abrasions. Use a soft pouch or a jewelry box with individual compartments to protect them. Avoid storing them in direct sunlight or in areas with high humidity, as this can affect their appearance and durability.
