July is unique among the calendar months, boasting not one, but two recognized birthstones: the vibrant ruby and the enigmatic onyx. While ruby has become the more widely recognized gem, particularly since its official designation in 1912, onyx retains a significant historical and cultural connection to the month. Both stones offer a compelling blend of beauty, history, and symbolism, reflecting the dynamic personalities of those born under the July sun. This article will explore the geological origins, historical significance, gemological properties, and cultural meanings associated with both the ruby and onyx, providing a comprehensive overview of July’s dual birthstone heritage.
A History Intertwined
The history of both ruby and onyx is deeply rooted in ancient civilizations. Ruby, known as the “king of precious stones” in ancient India, was revered for its rarity, hardness, and perceived mystical powers. Long associated with blood and the life force, it symbolized power and youthful energy, frequently adorning Indian jewelry. Ancient warriors, particularly in Burma, believed rubies rendered them invincible in battle, while medieval Europeans attributed to the gem the power to bestow health, wisdom, wealth, and success in love. The ruby’s association with July extends to modern traditions as well, being the traditional gift for the 15th and 40th wedding anniversaries.
Onyx also possesses a rich and lengthy history. For centuries, it was widely accepted as the primary birthstone for July, recognized in Jewish, Roman, and European traditions as early as the 15th century. Its historical prominence was officially superseded by ruby in the United States in 1912 by the National Association of Jewelers, though it continues to be acknowledged as an alternative or secondary birthstone. The stone’s connection to the zodiac sign Leo, which partially falls within July, further reinforces its symbolic link to the month.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, an aluminum oxide mineral. Its characteristic red hue is derived from trace amounts of the element chromium; the more chromium present, the more intense the red color. The most prized ruby color is a deep red with a hint of purple, known in the trade as “pigeon’s blood.”
The sources for ruby are varied, with historical significance attached to certain regions. While the provided sources do not detail specific mining locations beyond Burma, the mention of Burmese warriors and their belief in the stone’s protective qualities suggests a long-standing connection to that region.
Onyx, in contrast, is a banded variety of chalcedony, a microcrystalline form of silica. The sources do not provide information on the geological formation or specific mining locations of onyx.
Gemological Properties
Ruby distinguishes itself through its exceptional hardness, second only to diamond, making it a durable gemstone suitable for everyday wear. This durability, combined with its vibrant color, contributes to its desirability. The sources do not provide specific refractive index or other detailed gemological data.

Onyx, being a variety of chalcedony, possesses a different set of properties. It is known for its smooth, glossy surface and typically appears in deep black, though banded varieties also exist. The sources do not provide specific hardness or refractive index data for onyx.
Symbolism and Metaphysical Beliefs
Throughout history, both ruby and onyx have been imbued with symbolic meaning and metaphysical beliefs. Ruby, with its association with blood, has long been seen as a symbol of passion, vitality, courage, and love. Ancient cultures believed it could predict misfortune or danger, while others attributed to it the power to cure inflammatory diseases and soothe anger.
Onyx, similarly, carries a wealth of symbolism. It is often associated with strength, grounding, and protection. It is believed to absorb negative energy and is considered a stone that promotes self-control and confidence. The sources do not detail specific metaphysical beliefs associated with onyx beyond its reputation as a grounding stone.
The July Personality and Birthstone Connection

Cancerians (born June 21 – July 22) are specifically linked to the ruby, while Leos (born July 23 – August 22) find resonance with onyx.
Care and Cleaning
Due to its exceptional hardness, ruby is relatively durable and can withstand regular wear. Cleaning rubies is straightforward: warm, soapy water and a soft brush are generally sufficient. Avoid ultrasonic cleaners, as they may damage the stone.
