July, the month of warmth and vitality, is symbolized by three remarkable gemstones: the ruby, onyx, and turquoise. These stones, each with its own unique history, scientific properties, and cultural significance, have been cherished for centuries and continue to captivate gemstone lovers and jewelry wearers alike. This article explores the rich legacy and enduring allure of these July birthstones, drawing from authoritative sources to present a comprehensive overview grounded in gemological accuracy and historical insight.
The Ruby: A Gem of Passion and Power
The ruby is the primary birthstone for July and is celebrated as one of the most precious and valuable gemstones in the world. Its deep red color is due to the presence of the element chromium, which imparts a vivid hue that has captivated cultures across time. The finest rubies are known as "pigeon's blood" rubies, characterized by their deep red color with subtle purple undertones. The name "ruby" derives from the Latin word ruber, meaning "red," a fitting tribute to its striking appearance.
Historical Significance and Cultural Lore
Rubies have long been associated with power, passion, and protection. In Medieval Europe, they were believed to bring wisdom, wealth, and success in love. Some cultures even held the belief that rubies could predict misfortune or danger, serving as a kind of protective talisman. In Burmese tradition, warriors would wear rubies into battle, believing the stone made them invincible. These associations reflect the ruby's enduring status as a symbol of courage and strength.
The ruby's significance dates back centuries. Myanmar’s Mogok region has been a renowned source of high-quality rubies for over five hundred years. Other notable ruby-producing countries include Vietnam, Mozambique, Afghanistan, Tajikistan, Pakistan, Sri Lanka, Kenya, Tanzania, and Madagascar. These global sources have contributed to the ruby’s widespread popularity and its place as one of the four precious stones, alongside diamonds, emeralds, and sapphires.
Gemological Properties
Rubies belong to the corundum mineral family, which also includes sapphires. They are known for their exceptional hardness, ranking at 9 on the Mohs scale—second only to diamonds. This hardness makes rubies durable and suitable for everyday wear in jewelry. The ruby's refractive index ranges from 1.76 to 1.78, giving it a bright and lively appearance. Rubies can vary in color from pinkish-red to deep crimson, with the most valuable specimens displaying a "pigeon's blood" hue. They are often found in rough form in limestone and gem gravels.
Symbolism and Metaphysical Beliefs
Beyond their physical properties, rubies have been imbued with rich symbolism and metaphysical significance. In modern times, they are associated with love, devotion, and vitality. Ruby is believed to enhance courage, stimulate the heart chakra, and promote emotional healing. Historically, rubies were thought to bring prosperity and protection to the wearer, making them a popular choice for talismans and royal regalia.
Care and Cleaning
Due to their hardness, rubies are relatively easy to maintain. They can be cleaned with warm, soapy water and a soft cloth. Ultrasonic and steam cleaners are also safe for use. However, it is important to avoid exposing rubies to sudden temperature changes, as this can cause fractures. When storing ruby jewelry, it is best to keep the stones separate to prevent scratches from other gemstones or hard surfaces.
The Onyx: A Stone of Strength and Elegance
While the ruby holds the primary birthstone title for July, the onyx has also long been associated with the month and remains an important secondary birthstone. Onyx is a variety of chalcedony, a form of quartz, and is known for its striking contrast between white and dark bands. Historically, onyx has been linked to protection, strength, and emotional balance, making it a favored gemstone in both ancient and modern contexts.
Historical Significance and Cultural Lore
Onyx has a storied history that dates back to the 15th century, when it was widely recognized as the July birthstone in Jewish, Roman, and European traditions. In ancient Rome, onyx stones were often engraved with images of Mars, the god of war, or Hercules, and carried into battle as a source of courage and protection. Greeks and Romans also believed that onyx could guard against scorpion stings, an interesting parallel to its modern reputation as a stone of protection and strength.
In 1912, the National Association of Jewelers (now known as Jewelers of America) standardized a list of birthstones for the United States, officially replacing onyx with ruby as the primary July birthstone. Despite this change, onyx has retained its place as an alternative birthstone and is still valued for its bold appearance and grounding properties.
Gemological Properties
Onyx is a type of chalcedony, which is a microcrystalline variety of quartz. It has a hardness of 6.5 to 7 on the Mohs scale, making it suitable for everyday wear but requiring more care than the ruby. Onyx is typically opaque, with distinct banding patterns that can vary in color from white and black to brown and red. The banding is created by alternating layers of white chalcedony and sard, a darker form of carnelian.
Onyx is often cut into cabochons or used in engraved pieces due to its smooth, even texture. It is found in various parts of the world, including India, Brazil, and the United States. Its affordability and versatility have made it a popular choice for both jewelry and decorative objects.
Symbolism and Metaphysical Beliefs
Onyx is traditionally associated with emotional strength, discipline, and protection. It is believed to help the wearer absorb and neutralize negative energy, making it a valuable stone for those seeking emotional balance and resilience. In modern metaphysical practices, onyx is used to promote grounding, stability, and a sense of inner peace. It is also linked to the zodiac sign Leo, which spans part of July, further reinforcing its connection to the month.
Care and Cleaning
Onyx is relatively easy to clean and maintain. It can be wiped with a soft cloth and mild soap and water. Avoid using harsh chemicals or ultrasonic cleaners, as these can damage the stone. Onyx should also be stored separately from harder gemstones to prevent scratches. While onyx is durable, it is not as tough as ruby and should be handled with care to avoid chips or cracks.
The Turquoise: A Stone of Clarity and Spirit
Turquoise, another secondary birthstone for July, is a unique and captivating gemstone known for its blue-green color and opaque appearance. While it is more commonly associated with December, turquoise has long been recognized as a July birthstone in certain traditions. Its vibrant color and rich history have made it a beloved gemstone across cultures and centuries.
Historical Significance and Cultural Lore
Turquoise has been used for thousands of years and is one of the oldest known gemstones in human history. It has been found in archaeological sites in Egypt, Mesopotamia, and the Americas, where it was prized for its beauty and believed to possess protective and healing properties. In ancient Egypt, turquoise was associated with the gods and was used in jewelry and amulets to ward off evil and promote health.
In Native American traditions, turquoise is considered a sacred stone, often used in ceremonies and as a symbol of wisdom, protection, and spiritual clarity. It is believed to bring good fortune and promote positive communication. In Chinese culture, turquoise was known as the "heavenly stone" and was used in imperial jewelry and decorative objects.
Gemological Properties
Turquoise is a phosphate mineral composed of hydrated copper and aluminum. It is relatively soft, with a hardness of 5 to 6 on the Mohs scale, which means it requires careful handling and cleaning. The stone's color ranges from deep blue to green, with variations influenced by the presence of different minerals and impurities. Turquoise is often stabilized or treated with resin to enhance its durability and color.
Turquoise is typically opaque and is found in a variety of geological settings, including volcanic and sedimentary rocks. Major sources include the United States, China, Iran, and Egypt. Due to its softness and porous nature, turquoise is often set in protective settings to prevent damage.
Symbolism and Metaphysical Beliefs
Turquoise is associated with clarity of mind, emotional healing, and spiritual discernment. It is believed to help the wearer stay centered and focused, making it a popular stone for meditation and self-reflection. In modern metaphysical practices, turquoise is used to enhance communication, promote calmness, and encourage positive change. It is also thought to have protective qualities, shielding the wearer from negative influences.
Care and Cleaning
Because of its softness and porosity, turquoise requires gentle care. It should be cleaned with a soft cloth and mild soap and water, avoiding harsh chemicals and ultrasonic cleaners. Exposure to extreme heat, direct sunlight, and moisture should be minimized to prevent fading and damage. Turquoise jewelry should be stored in a cool, dry place, away from other gemstones that could cause scratches.
