History and Lore
Ancient Significance
The ruby has been revered for thousands of years, with its history dating back to ancient civilizations. In many cultures, the ruby was believed to possess protective qualities and was often worn by royalty and warriors for its supposed ability to bring strength and safety. Ancient texts from India, one of the earliest known sources of ruby mining, describe the gemstone as the "king of precious stones." In these cultures, the ruby was thought to be a gift from the gods and was associated with the sun, symbolizing power, vitality, and divine favor.
In ancient Egypt, rubies were used in jewelry and amulets, believed to bring good fortune and protection to the wearer. The gemstone was also highly valued in ancient Greece and Rome, where it was considered a symbol of life and love. The Romans associated the ruby with the goddess Venus and believed it could enhance passion and fertility. These beliefs laid the foundation for the ruby's continued significance in various cultures and its eventual designation as the birthstone for July.
Medieval and Renaissance Periods
During the medieval and Renaissance periods, the ruby remained a symbol of nobility and power. Kings and queens across Europe and the Middle East adorned themselves with ruby jewelry, often incorporating the gemstone into crowns, scepters, and other royal regalia. The ruby's deep red color was seen as a representation of blood and life, and it was believed to protect the wearer from harm, particularly in battle. In some cultures, rubies were also thought to have healing properties and were used in medicinal practices.
The ruby's association with love and passion continued to grow during this time, and it became a popular gemstone for romantic jewelry. Poets and artists often referenced the ruby in their works, further cementing its cultural significance. The gemstone's prominence in royal and religious artifacts also contributed to its enduring legacy, as it was frequently used in religious ceremonies and as part of sacred relics.
Modern Era and the Birthstone Tradition
The tradition of associating gemstones with the months of the year has its roots in ancient religious and cultural practices. One of the earliest recorded references to this tradition comes from the Bible, where the High Priest of Israel wore a breastplate adorned with twelve gemstones, each representing one of the twelve tribes of Israel. Over time, these twelve gemstones became associated with the twelve months of the year, and the ruby was assigned to July.
The modern concept of birthstones gained popularity in the 20th century, particularly after the publication of the first standardized list by the American National Association of Jewelers in 1912. This list designated the ruby as the official birthstone for July, a designation that has remained largely unchanged. The ruby's deep red color and symbolic meanings of love, courage, and vitality make it a fitting representation for July, the month of summer's peak.
Geological Formation and Sources
Formation of Rubies
Rubies are formed under intense heat and pressure deep within the Earth's crust, typically in metamorphic rocks such as marble. The presence of trace amounts of chromium or vanadium in the mineral corundum is what gives rubies their characteristic red color. Corundum, the mineral family to which rubies belong, is the same material that forms sapphires when it contains trace amounts of iron and titanium instead of chromium.
The process of ruby formation begins with the deposition of corundum in sedimentary rocks. Over millions of years, these rocks are subjected to high temperatures and pressures, causing them to undergo metamorphism. During this process, the corundum crystals grow and develop their red color due to the presence of chromium. The conditions required for ruby formation are rare, which is why high-quality rubies are considered among the most valuable gemstones in the world.
Major Sources of Rubies
The most well-known source of high-quality rubies is Myanmar, formerly known as Burma. For over 500 years, the Mogok region in Myanmar has been a leading producer of rubies, particularly those with the coveted "pigeon blood" color. The rubies from this region are known for their deep red color, excellent clarity, and strong fluorescence, which enhances their brilliance.
In addition to Myanmar, rubies are also found in other parts of the world, including Thailand, Vietnam, and Sri Lanka. The Chanthaburi region in Thailand is another significant source of rubies, although the quality of rubies from this area is generally lower than those from Myanmar. Vietnamese rubies are often red to purple-red in color and are found in the northern mountainous regions of the country.
Sri Lankan rubies are known for their vibrant red color and excellent clarity, but they tend to have a slightly different hue compared to Burmese rubies. These differences in color and quality are often used by gemologists to identify the origin of a ruby.
Alternative July Birthstones
While the ruby is the primary birthstone for July, there are also alternative gemstones that are associated with the month. These include carnelian, onyx, and turquoise, each of which brings its own unique properties and symbolism.
Carnelian is a vibrant orange-red gemstone that is often used as an alternative July birthstone. It is known for its warmth and is believed to promote creativity and energy. Carnelian is a type of chalcedony and is found in various parts of the world, including India, Brazil, and the United States.
Onyx is a banded form of chalcedony that is often black or white in color. It is associated with protection and grounding and is believed to help the wearer stay centered and focused. Onyx is found in countries such as Brazil, India, and the United States.
Turquoise is a blue-green gemstone that is also considered an alternative July birthstone. It is known for its calming properties and is believed to promote clarity of mind and spiritual discernment. Turquoise is found in various parts of the world, including the United States, China, and Iran.
Gemological Properties
Physical and Chemical Characteristics
The ruby is a member of the corundum family, which is composed of aluminum oxide (Al₂O₃). The presence of trace amounts of chromium or vanadium is what gives rubies their red color. The chemical composition of rubies can vary slightly depending on their source, which can affect their color and other properties.
In terms of physical properties, rubies are known for their hardness and durability. On the Mohs scale of mineral hardness, which ranges from 1 (softest) to 10 (hardest), rubies have a hardness of 9, making them one of the hardest gemstones. This high hardness makes rubies suitable for use in a variety of jewelry settings, including rings, bracelets, and necklaces.
The refractive index of rubies is also quite high, typically ranging from 1.76 to 1.78. This high refractive index contributes to the gemstone's brilliance and fire, making it a popular choice for jewelry. Rubies can also exhibit a phenomenon known as asterism, where a star-like pattern is visible under certain lighting conditions. This effect is caused by the presence of tiny needle-like inclusions within the gemstone.
Color and Clarity
The color of a ruby is one of its most defining characteristics. The most valuable rubies are those with a deep red color that is often described as "pigeon blood red." This term refers to a specific shade of red that is rich, vibrant, and has a slight blue undertone. The color of a ruby can vary depending on the source and the trace elements present in the gemstone. For example, rubies from Myanmar are known for their intense red color, while those from Thailand may have a more pinkish hue.
Clarity is another important factor in evaluating the quality of a ruby. High-quality rubies are typically free of visible inclusions, but it is rare to find a completely flawless ruby. Inclusions are natural features that occur during the formation of the gemstone and can affect its appearance and value. Some inclusions are so small and well-hidden that they do not detract from the gemstone's beauty, while others may be more noticeable and reduce its value.
Cut and Carat
The cut of a ruby is crucial in determining its brilliance and overall appearance. Rubies are often cut into shapes such as round, oval, cushion, and emerald cuts, depending on the desired effect. The cut can also affect the gemstone's durability, as certain cuts may be more prone to chipping or breaking.
The carat weight of a ruby is another factor that influences its value. Larger rubies are generally more valuable, but the overall quality of the gemstone is also a key consideration. A smaller ruby with excellent color and clarity may be more valuable than a larger ruby with inclusions or a less desirable color.
Symbolism and Metaphysical Beliefs
Historical and Cultural Symbolism
The ruby has been associated with a wide range of symbols and meanings throughout history. In many cultures, the ruby was believed to be a symbol of life, vitality, and passion. Its deep red color was often linked to the heart and was thought to promote love and emotional well-being. In ancient times, rubies were also believed to have protective qualities and were used in amulets and talismans to ward off evil and bring good fortune.
In India, the ruby was considered a sacred stone and was associated with the sun god Surya. It was believed to bring prosperity, health, and success to the wearer. In Chinese culture, rubies were thought to bring good luck and were often used in ceremonial jewelry and decorations. In Europe, the ruby was associated with royalty and was often used in royal regalia and crowns.
Metaphysical Properties
In addition to its historical and cultural symbolism, the ruby is also associated with a range of metaphysical properties. Many people believe that rubies have healing properties and can help with physical, emotional, and spiritual well-being. It is said that rubies can stimulate the heart and circulatory system, promoting vitality and energy. They are also believed to help with emotional healing, particularly in matters of love and relationships.
Rubies are thought to enhance courage and confidence, making them a popular choice for those who need to face challenges or make important decisions.

Care and Cleaning
General Care Tips
Rubies are durable gemstones, but they still require proper care to maintain their beauty and longevity. Because rubies have a hardness of 9 on the Mohs scale, they are resistant to scratches and can be worn in everyday jewelry settings. However, they can still be damaged if exposed to harsh chemicals or extreme temperatures.
To clean a ruby, it is best to use a gentle solution of warm water and mild dish soap. A soft brush can be used to gently scrub the gemstone, and a soft cloth can be used to dry it. It is important to avoid using harsh chemicals such as bleach or ammonia, as these can damage the gemstone or its setting.
Rubies should also be stored separately from other gemstones to prevent scratches. It is best to store them in a soft pouch or a jewelry box with individual compartments. When not in use, rubies should be kept in a cool, dry place away from direct sunlight, which can cause the gemstone to fade over time.
Avoiding Damage
While rubies are hard and durable, they can still be damaged under certain conditions. For example, rubies can be sensitive to heat, and exposure to high temperatures can cause them to crack or lose their color. It is important to avoid exposing rubies to extreme heat, such as from a fire or a hot stove.
Rubies can also be sensitive to ultrasonic cleaners, which use high-frequency vibrations to clean gemstones. These cleaners can cause damage to rubies, particularly if the gemstone has inclusions or is treated with heat or chemicals. It is best to avoid using ultrasonic cleaners on rubies and to opt for a gentler cleaning method instead.
In addition, rubies should be removed before engaging in activities that involve heavy physical contact, such as sports or manual labor. This can help prevent the gemstone from being chipped or scratched.
