This article will delve into the ruby’s history, geological origins, gemological properties, cultural significance, and care, providing a comprehensive overview of this remarkable July birthstone.
History and Lore
The ruby’s history stretches back millennia, with its earliest origins rooted in ancient civilizations. In ancient India, the ruby was revered as the “king of precious stones,” celebrated for its rarity, exceptional hardness – second only to diamond – and perceived mystical powers. It was considered a symbol of power and youthful energy, frequently incorporated into Indian jewelry. Ancient beliefs attributed various properties to the ruby, including the ability to predict misfortune, cure inflammatory diseases, and even soothe anger. Burmese warriors believed possessing a ruby rendered them invincible in battle, a testament to the stone’s association with courage and protection.
Medieval Europeans similarly held the ruby in high regard, believing it bestowed health, wisdom, wealth, and success in love. The ruby’s association with royalty and nobility further cemented its status as a gemstone of prestige and power. Throughout the centuries, the ruby has remained a symbol of passion and devotion, traditionally gifted to commemorate the 15th and 40th wedding anniversaries. The concept of birthstones, while evolving over time, finds its roots in ancient traditions, potentially originating from the twelve gemstones in the Biblical Breastplate of Aaron, with the assignment of gems to specific months solidifying during the Middle Ages. The American National Retail Jewelers Association standardized a list of birthstones in the 20th century, further popularizing the ruby’s association with July.
Geological Formation and Sources
Rubies are formed through a complex geological process involving high pressure and temperature. As a variety of corundum (aluminum oxide), rubies crystallize in metamorphic and igneous rocks. The presence of chromium during the formation process is crucial, as it imparts the characteristic red color. The intensity of the red hue is directly proportional to the amount of chromium present.
While rubies have been discovered in various locations worldwide, certain regions are particularly renowned for their production of high-quality stones. Myanmar (Burma) has historically been the most significant source of exceptional rubies, particularly those exhibiting the coveted “pigeon’s blood” color. Other notable sources include Thailand, Sri Lanka, Madagascar, Mozambique, and Tanzania. The specific geological conditions and trace element composition in each location contribute to the unique characteristics of the rubies found there.
Gemological Properties
The ruby’s allure stems not only from its color but also from its exceptional physical and optical properties.

As indicated in the table, ruby boasts a hardness of 9 on the Mohs scale, making it exceptionally durable and suitable for everyday wear. Its high refractive index contributes to its brilliance and fire, while its specific gravity distinguishes it from other similar-looking gemstones. Rubies exhibit a range of red shades, from orangish-red to purplish-red, with the most valuable possessing a vivid, pure red color. Clarity can vary, with some rubies exhibiting inclusions (internal imperfections) that can affect their value. However, certain inclusions, known as “silk,” can enhance a ruby’s appearance by scattering light and creating a velvety texture.
Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been imbued with rich symbolism and metaphysical beliefs. As previously mentioned, it has long been associated with love, passion, and courage. The ruby’s connection to blood further reinforces its symbolism of life force, vitality, and energy.

Some traditions suggest that rubies can stimulate the heart chakra, fostering emotional healing and promoting feelings of love and compassion.
Beyond its traditional symbolism, the ruby is also associated with leadership, ambition, and success. It is believed to inspire confidence, creativity, and a zest for life. For those born in July, the ruby is considered a talisman of good fortune, empowering them to pursue their dreams with passion and determination.
Alternative Birthstones and Zodiac Associations
While the ruby is the traditional July birthstone, alternative gemstones are also associated with the month. These include carnelian, citrine, garnet, and onyx. The inclusion of these alternatives reflects the evolving nature of birthstone traditions and the diverse preferences of individuals. Onyx, in particular, is highlighted as an alternative, embodying strength and sophistication.
Furthermore, the ruby is linked to specific zodiac signs within July: Cancer (June 21 – July 22) and Leo (July 23 – August 22). The ruby is considered the birthstone for Cancer, complementing their nurturing and passionate nature. For Leos, peridot is the associated gemstone, mirroring their fiery energy and vibrant personality.
Care and Cleaning
Due to its exceptional hardness, the ruby is a relatively durable gemstone. However, proper care is essential to maintain its brilliance and prevent damage. Rubies should be cleaned regularly with warm, soapy water and a soft brush. Avoid harsh chemicals, ultrasonic cleaners, and steam cleaners, as these can potentially damage the stone or its setting. It is also advisable to remove ruby jewelry before engaging in strenuous activities or when exposed to abrasive materials. Regular inspection of the setting is recommended to ensure the ruby is securely held in place.
