Green onyx is a captivating gemstone associated with August, offering a rich history and a range of purported benefits to those born within this month. While peridot and spinel also represent August, green onyx holds a unique position as the “ancient” birthstone for this time of year, steeped in tradition and believed to promote equilibrium and well-being. This article will explore the history, geological origins, gemological properties, symbolism, and practical care of this intriguing green variety of chalcedony.
History and Lore
The history of birthstones is interwoven with cultural beliefs and evolving traditions. The practice of associating specific gems with birth months gained prominence during the Victorian era, though lists of official birthstones were formalized later in the mid-twentieth century by organizations like the National Association of Jewelers. These lists have been updated over time to reflect changing tastes and the discovery of new gems. Green onyx, however, has a long-standing connection to August, representing a more ancient tradition.
The name “onyx” itself originates from the Greek word ónyx, meaning “nail” or “claw,” a reference to the banded patterns within the stone that can resemble fingernails. While black onyx is more commonly recognized, the green variety offers a distinct appeal. Green onyx has been utilized in jewelry for centuries, valued for its aesthetic qualities and believed metaphysical properties.
Geological Formation and Sources
Green onyx is a form of chalcedony, a microcrystalline variety of silica. It is created through an intricate geological process involving the deposition of silica from silica-rich solutions within volcanic or metamorphic rocks. The banding characteristic of onyx, including green onyx, is formed by alternating layers of chalcedony differing in color and composition.
The sources of green onyx are not specifically detailed in the provided materials. However, chalcedony, the broader mineral family to which green onyx belongs, is found in numerous locations worldwide. The materials emphasize the availability of green onyx for use in jewelry, suggesting it is sourced from locations where chalcedony is commonly mined.
Gemological Properties
Green onyx is known for its rich, dark green hue. It is a translucent to opaque gemstone, exhibiting a vitreous luster. As a variety of chalcedony, it possesses a Mohs hardness of 6.5 to 7, making it relatively durable but still susceptible to scratches. The chemical composition of onyx is silicon dioxide (SiO2).
The provided sources do not detail the refractive index, specific gravity, or other advanced gemological properties of green onyx. However, its classification as chalcedony provides a general understanding of its physical characteristics. Green onyx is often cut and polished into cabochons, beads, and other ornamental shapes, showcasing its smooth texture and banded patterns.
Symbolism and Metaphysical Beliefs
Throughout history, gemstones have been attributed with symbolic meanings and metaphysical properties. Green onyx is believed to carry equilibrium and soundness to the wearer, making it a popular choice for those seeking a grounding stone. It is thought to bridge the upper and lower chakras, connecting the heart chakra and promoting emotional balance.
Some believe green onyx fosters self-confidence and relieves tension. It is associated with strength, discipline, and willpower. The stone’s connection to nature is also emphasized, representing growth and a connection to the natural world. These beliefs contribute to its appeal as a birthstone for August, a month often associated with reflection and renewal.

The materials suggest that green onyx jewelry is available in a wide range of styles, from classic and sophisticated to more intricate and eye-catching designs. Sterling silver is a frequently used metal setting for green onyx, complementing the stone’s green tones.
