History and Lore
The ruby has long been associated with power, passion, and protection. Historically, it was believed to bring good fortune and ward off evil. Ancient cultures, including those in India, Burma, and Thailand, considered the ruby a sacred stone. In many traditions, ruby was associated with the sun and was thought to possess healing properties.
In modern times, ruby has retained its symbolic significance. It is often linked with love, vitality, and courage. As the birthstone for July, it is a popular choice for those born in that month, symbolizing a bold and passionate spirit.
Ruby’s journey to becoming an official birthstone is rooted in both historical and commercial traditions. While it is not clear when ruby was first designated as the July birthstone, its association with the month is well established in contemporary jewelry markets. Several sources indicate that ruby is the primary birthstone for July, with onyx and turquoise also being considered as alternatives in some contexts.
The ruby’s historical use in jewelry spans centuries. It has been found in ancient royal treasures and is still a favored gemstone in high-end jewelry collections today. In particular, ruby earrings are a popular choice for those seeking to incorporate the gemstone into their jewelry repertoire.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The characteristic red color of ruby is due to the presence of trace amounts of chromium. This element replaces some of the aluminum atoms in the crystal structure, resulting in the deep red hue for which ruby is known.
The formation of ruby involves high-pressure and high-temperature conditions, typically found in metamorphic rock environments. These conditions are essential for the development of ruby’s crystalline structure and its intense color.
Historically, some of the most famous ruby sources include Burma (now Myanmar), Thailand, Sri Lanka, and India. These regions have produced some of the finest rubies in the world, particularly those with a deep, vivid red color known as "pigeon's blood." However, ruby is also found in other parts of the world, including Afghanistan, Tanzania, and Madagascar.
In terms of jewelry production, ruby is often sourced from various mines around the world. However, the quality of the ruby, rather than its source, is the primary factor in determining its value. As noted in some sources, even the best mines can produce rubies of lower quality, and the majority of rubies on the market have undergone treatments to enhance their appearance.
Ruby is a relatively durable gemstone, with a hardness of 9 on the Mohs scale. This makes it suitable for use in various types of jewelry, including earrings, which are subject to frequent handling. However, like many gemstones, ruby can contain inclusions, which are natural imperfections that can affect its clarity and value.

Ruby is typically found in a range of sizes, from small gemstones used in earrings to larger stones in pendants and rings. The price of ruby can vary significantly based on factors such as color, clarity, and size. High-quality rubies with intense color and minimal inclusions can command very high prices, often reaching up to $1,000,000 per carat.
In the context of jewelry, ruby is often set in gold, silver, or platinum. These metals provide a complementary setting that enhances the gemstone’s brilliance and durability. Ruby earrings, for example, are commonly made with 14-karat gold, which offers a balance between strength and beauty.
Symbolism and Metaphysical Beliefs
The ruby has long been associated with various symbolic and metaphysical meanings across different cultures. In many traditions, it is seen as a stone of power and protection. It is often linked to the heart and is believed to promote love, passion, and emotional strength.
In ancient times, ruby was considered a sacred stone. It was believed to bring good fortune, ward off evil, and provide protection to the wearer. Some cultures also associated ruby with the sun and believed it to possess healing properties.

Care and Cleaning
Like all gemstones, ruby requires proper care to maintain its beauty and longevity. While ruby is a relatively durable gemstone, it can still be damaged if not handled properly. Here are some tips for caring for ruby jewelry, particularly ruby earrings:
- Cleaning: Ruby can be cleaned with warm water and mild soap. A soft, damp cloth can also be used to gently wipe the surface of the gemstone. Avoid using harsh chemicals, such as bleach or ammonia, as these can damage the stone or the metal setting.
- Avoiding Chemicals: It is important to keep ruby jewelry away from perfumes, hairsprays, and other chemicals. These substances can dull the gemstone's surface and potentially damage the metal setting.
- Storing: To prevent scratches and damage, ruby jewelry should be stored separately from other pieces, especially those with sharp edges. A soft pouch or a jewelry box with individual compartments is ideal.
- Wearing: While ruby is durable, it is still advisable to avoid wearing ruby jewelry during activities that could cause physical impact, such as sports or heavy lifting.
For ruby earrings, it is also important to be mindful of how they are worn and removed. Earrings should be handled gently to avoid bending the earring posts or damaging the gemstone. Regular inspections can help identify any signs of wear or damage, such as loose settings or broken posts.
By following these care tips, ruby jewelry can remain beautiful and functional for many years.
