Ruby, the vibrant red gemstone, has long been cherished as a symbol of love, vitality, and passion. As the birthstone for those born in July, it carries a rich historical legacy and a deep connection to human emotion and symbolism. This article explores the ruby in detail, examining its historical significance, geological properties, and its enduring presence in fine jewelry — particularly in gold. Drawing from multiple sources, it provides a comprehensive overview of ruby’s allure, both as a gemstone and as a meaningful piece of jewelry.
History and Lore
Ruby’s history spans millennia, with its vivid red color often associated with the sun, life force, and divine energy. Known as the "King of Gems," ruby has been revered across cultures for its fiery brilliance and symbolic power.
The ruby was considered a sacred gemstone in ancient civilizations. In India, it was believed to be a divine gift, embodying the blood of the gods and the sun itself. Ancient texts from as early as 400 BCE mention the ruby’s ability to bring good fortune and protection. In China, ruby was used in imperial regalia, and it was believed to promote health and longevity. Similarly, in Burma (now Myanmar), ruby was so highly valued that it was said to be guarded by dragons, with the most famous ruby mine located in the Mogok region.
In the West, ruby was associated with love and the heart. During the Middle Ages, European royalty and clergy often wore ruby rings, believing that the gemstone could protect them from poison and disease. It was also thought to inspire courage and promote fidelity in love. The ruby’s connection with passion and power has endured through the centuries, making it a popular choice for engagement and anniversary rings.
As a birthstone, ruby was officially recognized in the United States in 1912 by the American National Association of Jewelers. It is considered the birthstone for July and is also associated with the 15th, 40th, and 80th wedding anniversaries. This recognition has helped cement its place in modern jewelry traditions.
Geological Formation and Sources
Ruby is a type of corundum, which is an aluminum oxide (Al₂O₃) mineral. What distinguishes ruby from other corundum varieties is the trace amount of chromium, which gives it its characteristic red color. The presence of iron can modify the color, sometimes resulting in a pinkish hue, which is then classified as a pink sapphire rather than a ruby.
The formation of ruby requires specific geological conditions. Ruby is typically found in metamorphic rocks, where extreme heat and pressure have transformed existing minerals. These conditions are most commonly found in regions with a history of tectonic activity. The most famous ruby-producing region is Myanmar, particularly the Mogok region, which is often referred to as the "Valley of Rubies." Other notable sources include Thailand, Sri Lanka, Tanzania, and Madagascar.
The ruby’s vibrant color and hardness (9 on the Mohs scale) make it a desirable gemstone for jewelry. Its durability allows it to be cut into various shapes, from traditional round and oval cuts to more intricate designs that highlight the gemstone’s brilliance.
Gemological Properties
Ruby is one of the most valuable and sought-after gemstones in the world, thanks to its combination of beauty, rarity, and durability. Here are some key gemological properties of ruby:
- Chemical Formula: Al₂O₃ (with trace amounts of chromium or vanadium)
- Hardness (Mohs Scale): 9
- Refractive Index: 1.76–1.78
- Color: Red, ranging from deep crimson to lighter shades depending on chromium content
- Luster: Vitreous (glassy)
- Transparency: Transparent to translucent
- Crystal System: Hexagonal
- Cleavage: None (but may have fractures)
- Specific Gravity: 4.00–4.10
In terms of cutting, ruby is often cut into round, oval, or cushion shapes to maximize its brilliance and color. Some ruby jewelry features gemstones that are heat-treated or irradiated to enhance their color and clarity. These treatments are common and are generally considered acceptable in the gem trade.
The value of a ruby depends on several factors, including its color, clarity, cut, and carat weight. A high-quality ruby with a vivid red color and minimal inclusions is extremely rare and can command high prices in the market. The most valuable rubies are typically those from Myanmar, especially those with a "pigeon’s blood" red color, a term used to describe the purest and most intense ruby red.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful metaphysical properties and symbolic meanings. In many cultures, it is believed to represent life, passion, and vitality. The ancient Greeks referred to ruby as "Lithias," which means "king of gems," and believed it could protect the wearer from harm and promote courage.
In modern times, ruby is often considered a stone of love and devotion. It is frequently used in engagement rings and anniversary gifts to symbolize enduring love and commitment. Some believe that ruby can enhance emotional strength and help individuals express their feelings more openly.
Ruby is also associated with energy and motivation. It is believed to stimulate the heart chakra, promoting emotional balance and strength. Some practitioners use ruby in meditation to enhance vitality and creativity. It is also thought to bring good fortune and success in business and personal endeavors.
While these beliefs are rooted in tradition and spiritual practices, it is important to note that gemstones do not possess inherent magical powers. However, the symbolic and emotional significance of ruby continues to make it a popular choice for meaningful jewelry.
Ruby in Jewelry: Design and Craftsmanship
Ruby rings are a popular choice for those seeking a meaningful and elegant piece of jewelry. The ruby’s vibrant color and durability make it ideal for everyday wear, and its association with love and passion make it a fitting choice for engagement rings, anniversary gifts, and personal adornment.
In the jewelry industry, ruby is often set in gold, which complements its warm color and provides a strong, durable setting. The sources consulted in this article highlight several examples of ruby rings crafted in 14k and 18k gold, emphasizing the importance of craftsmanship and quality in fine jewelry.
One example is a 14k gold ruby ring featuring a 0.45 carat ruby set in a polished gold band with rhodium plating for added shine. Another design features a 9-carat solid gold ruby ring with a bezel setting that securely holds the gemstone in place. These rings are crafted to highlight the ruby’s beauty while ensuring long-lasting wear.
Ruby rings can be designed in a variety of styles, from classic and minimalist to bold and ornate. Some rings feature ruby as the central gemstone, while others combine it with diamonds or other gemstones to create a unique look. The versatility of ruby allows it to be incorporated into a wide range of jewelry designs, from simple bands to elaborate statement pieces.
In addition to its aesthetic appeal, ruby jewelry is often crafted with attention to detail and ethical sourcing. Many jewelers emphasize the use of ethically sourced gemstones and gold, ensuring that their products are both beautiful and responsible. Hallmarking by the Assay Office, as mentioned in some of the sources, provides assurance of the gold’s purity and authenticity.
Care and Cleaning
Ruby is a durable gemstone with a hardness of 9 on the Mohs scale, making it suitable for everyday wear. However, like all gemstones, it requires proper care to maintain its beauty and longevity.
To clean ruby jewelry, use a soft brush, warm water, and mild detergent. Gently scrub the gemstone and the metal setting, then rinse thoroughly and dry with a soft cloth. Avoid using harsh chemicals or ultrasonic cleaners, as they can potentially damage the gemstone or its setting.
When storing ruby jewelry, keep it in a soft pouch or a jewelry box to prevent scratches and abrasions. Avoid storing it with other gemstones that may scratch the ruby, especially those with a lower hardness rating. It is also advisable to remove ruby jewelry before engaging in activities that may expose it to impact or abrasive surfaces.
If the ruby is set in a delicate or intricate setting, it is best to have it professionally cleaned and inspected by a jeweler. This is particularly important for rings that are worn frequently, as the setting may need periodic tightening or maintenance to ensure the gemstone remains secure.

Ruby, with its deep red color and enduring symbolism, remains a timeless gemstone that continues to captivate jewelry lovers and gemologists alike. As the birthstone for July, it carries a rich historical legacy and a profound connection to human emotion and meaning. Whether worn as a personal talisman or a gift of love, ruby rings crafted in gold combine beauty, durability, and craftsmanship to create pieces that are both meaningful and lasting.
From its geological formation in the earth’s crust to its role in jewelry and cultural traditions, ruby is a gemstone of exceptional value. Its vibrant color and symbolic significance make it a perfect choice for those seeking a meaningful and elegant piece of jewelry. As the sources highlight, ruby rings are not only beautiful but also crafted with attention to detail and quality, ensuring their place in both personal collections and fine jewelry traditions.
