July is a month celebrated with vibrant energy, and fittingly, it boasts not one, but two recognized birthstones: the captivating ruby and the enigmatic onyx. While ruby holds the position as the most widely recognized modern birthstone, onyx maintains a timeless appeal and historical significance. Both gems offer a unique beauty and a rich history, making July birthdays particularly special. This article will delve into the history, geological origins, gemological properties, symbolism, and care of these two remarkable gemstones.
A History Intertwined with Lore
The history of both ruby and onyx stretches back millennia, interwoven with tales of power, protection, and passion. Ruby, known as the “king of precious stones” in ancient India, was revered for its rarity, beauty, and perceived mystical powers. Its name originates from the Latin word ruber, meaning “red,” a color long associated with life, vitality, and love. Ancient Indian jewelry frequently featured rubies, symbolizing power and youthful energy. Warriors in Burma believed the gem rendered them invincible in battle, while medieval Europeans attributed to it the power to bestow health, wisdom, wealth, and success in love. The ruby is also traditionally associated with the 15th and 40th wedding anniversaries, signifying enduring passion and commitment.
Onyx, while not as consistently highlighted as ruby in the provided sources, also carries a significant historical weight. In ancient Rome and Greece, sardonyx – a variety of onyx – was often engraved with images of Mars, the god of war, or Hercules, and carried into battle for protection and strength. There was even a belief that it could ward off scorpion bites. This association with protection and strength continues to resonate in modern interpretations of the stone’s meaning.
The distinction between modern and traditional birthstones explains the dual designation for July. The Jewelers of America officially designated modern birthstones in the 1950s, while traditional birthstones were widely accepted earlier in the 20th century and even before. As some traditional gems became rarer, the modern designations provided more readily available alternatives.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, and its vibrant red hue comes from trace amounts of the element chromium. The more chromium present, the more intense the red color. The finest ruby color is a deep red with a hint of purple, often referred to as “pigeon’s blood” by gem traders. The sources for ruby are not detailed extensively in the provided materials, but the text mentions Burma as a historical source.
Onyx, and its relative sardonyx, are forms of chalcedony, a microcrystalline variety of silica. Sardonyx is a combination of sard and onyx, exhibiting bands of reddish-brown and lighter shades like orange or white. The sources indicate that both onyx and sardonyx were valued in ancient times, connecting wearers to the civilizations of Ancient Rome and Greece.

Symbolism and Metaphysical Beliefs
Both ruby and onyx are imbued with rich symbolism. Ruby, as the “stone of kings,” represents passion, courage, and vitality. It has been historically associated with protection from misfortune and the ability to soothe anger. Some believed it could even predict danger. Modern interpretations continue to emphasize its connection to love, energy, and motivation.
Onyx, particularly sardonyx, is strongly linked to protection and strength. Ancient warriors carried it into battle, believing it would grant them courage and safeguard them from harm. Modern beliefs suggest onyx can ward off depression and boost self-confidence, connecting to the sacral chakra. Moonstone, also listed as a July birthstone, is associated with solidified moonbeams in Hindu mythology and was favored by designers like Louis Comfort Tiffany. Emerald, a zodiac stone for July, was considered a gift from God to Solomon and used in religious ceremonies by the Incas.
Care and Cleaning
Due to its exceptional hardness, ruby is a durable gemstone suitable for everyday wear. Cleaning can be done with warm, soapy water and a soft brush. Avoid ultrasonic cleaners, as they may damage the stone. Onyx, being a softer stone, requires more gentle care. Avoid harsh chemicals and abrasive cleaners. Cleaning with a soft cloth and mild soapy water is recommended.
Conclusion
The July birthstones, ruby and onyx, represent a captivating blend of history, beauty, and symbolism. Ruby, the “king of precious stones,” embodies passion, courage, and vitality, while onyx offers protection and strength.
