July’s birthstones, ruby and onyx, offer a striking contrast of fire and fortitude. The ruby, with its deep red brilliance, symbolizes love, courage, and vitality—once treasured by royalty and warriors alike. Onyx, with its sleek black elegance, represents protection, confidence, and resilience. Both July’s birthstones carry rich historical and symbolic weight, making them enduring choices for meaningful jewelry and personal adornment.
1. Historical Origins of July’s Birthstones
The stories of ruby and onyx stretch across empires and eras, each layer of their history revealing why they became July’s birthstones. Rubies, celebrated as the “king of gems,” pulsed with life in ancient texts, while onyx served as both armor and artistry. These stones weren’t merely adornments—they were cultural touchstones, their meanings etched into rituals and regalia.
Ruby’s Regal Pedigree
To hold a ruby was to grasp a piece of the divine. Sanskrit poets called it “ratnaraj” (“king of gems”); medieval knights believed it could deflect arrows, and Renaissance painters ground its powder to depict sacred wounds. By 1912, its fiery hue made it the natural choice for July’s birthstones—a symbol of vitality still sought after in fine jewelry today.
Onyx’s Protective Legacy
Onyx’s power lay in its contrasts: a stone of mourning and might. Mesopotamians carved it into seals to authenticate decrees; Roman generals wore it to channel Mars’ ferocity, and Victorians set it in jet-black rings to honor the departed. Its bold elegance continues to resonate, a testament to its enduring symbolic weight.
Why Does July Have Two Birthstones?
The duality of ruby and onyx reflects humanity’s love of layered meaning. Ruby, July’s modern birthstone, embodies summer’s zenith, while onyx preserves ancient ties to Leo season and older calendrical systems. Together, they offer a choice between fire and fortitude—two sides of July’s spirit.

3. Symbolism & Modern Appeal
Ruby: The Stone of Fire & Life
Rubies have long been seen as vessels of vitality. Burmese warriors believed they granted invincibility, while ancient Hindus associated them with the sun’s eternal flame. Even in darkness, their deep crimson hue appears to glow, which led some cultures to view them as protective talismans. (Interestingly, legends claimed a ruby’s color would dim to warn of approaching danger, then reignite once the threat passed.) Today, this mesmerizing depth makes them a timeless symbol of passion, whether set in heirloom pieces or contemporary designs.
Onyx: The Stone of Strength & Contrast
Onyx’s bold, layered appearance has symbolized duality across cultures—both a shield against harm and a canvas for artistry. The ancient Persians carved it into amulets to deflect negativity, while Art Deco jewelers used its stark bands to create striking geometric patterns. Modern wearers value it as much for its grounding energy as its sleek versatility, making it a favorite for both statement pieces and understated elegance.
