July is richly endowed with birthstone options, but the ruby stands out as the primary gem associated with this month. Revered for its vibrant red hue and historical significance, the ruby has captivated cultures for millennia. This article delves into the history, lore, geological origins, gemological properties, and symbolism of the ruby, exploring its enduring appeal as a gemstone and its special connection to those born in July. While other gems like sapphire, topaz, agate, and beryl are also linked to July birthdays, this article will focus primarily on the ruby, as it is consistently identified as the principal July birthstone.
History and Lore
The ruby’s history is deeply intertwined with human civilization, stretching back to ancient times. In ancient India, the ruby was esteemed as the “king of precious stones,” prized for its rarity, beauty, and perceived mystical powers. It was believed to embody the life force, represented by its blood-red color, and was a symbol of power and youthful energy, frequently featured in Indian jewelry.
Ancient Burmese warriors held the ruby in high regard, believing it rendered them invincible in battle. Medieval Europeans attributed a range of benefits to the ruby, including bestowing health, wisdom, wealth, and success in love. The gem was also thought to be capable of predicting misfortune or even curing inflammatory diseases and calming anger.
The association of rubies with July as a birthstone evolved over time, stemming from ancient traditions linking gemstones to the twelve gemstones in the Biblical Breastplate of Aaron. This concept developed through the Middle Ages, with each stone becoming connected to a specific month or zodiac sign. In the 20th century, the American National Retail Jewelers Association standardized a list of birthstones, solidifying the ruby’s position as the primary gem for July. Beyond its birthstone status, the ruby is traditionally gifted to celebrate the 15th and 40th wedding anniversaries, symbolizing enduring passion and devotion.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, renowned for its exceptional hardness – second only to diamond. Its characteristic red color arises from trace amounts of the element chromium present during its formation. The intensity of the red is directly proportional to the amount of chromium; the most desirable color, known as “pigeon’s blood,” is a deep, rich red with a hint of purple.
Rubies form in metamorphic and igneous rocks. Specifically, they are often found in marble, schist, and gneiss, formed under conditions of high pressure and temperature. The sources of rubies are geographically diverse, though certain regions are particularly renowned for their quality. While the provided sources do not detail specific mining locations beyond mentioning Burma (Myanmar), the historical significance of Burmese rubies is highlighted.
Gemological Properties
The ruby’s gemological properties contribute to its desirability and value.

| Hardness | 9 (Mohs scale) |

The ruby’s hardness of 9 on the Mohs scale makes it exceptionally durable, suitable for everyday wear. Its adamantine luster gives it a brilliant, sparkling appearance. The refractive index contributes to its vibrant color and fire. The gem’s color is the most significant factor in determining its value, with the “pigeon’s blood” hue commanding the highest prices.
Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been imbued with rich symbolism. As mentioned previously, its red color has long been associated with blood, life, passion, and power. In ancient cultures, it was believed to offer protection against evil and misfortune. Some believed the ruby could predict danger, while others attributed healing properties to the gem, claiming it could alleviate inflammatory diseases and soothe anger.
Modern metaphysical beliefs continue to associate the ruby with vitality, courage, and motivation. It is often considered a stone of passion, enhancing energy and promoting a positive outlook. The ruby is also believed to stimulate the heart chakra, fostering love, compassion, and emotional healing.

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 gem. It is also advisable to remove ruby jewelry before engaging in strenuous activities to prevent scratches or impacts. Given its hardness, a ruby can scratch other gemstones, so it’s best to store it separately from softer gems.
