The ruby, known as the July 22nd birthstone, is a gemstone of profound historical and cultural significance. Renowned for its vibrant red hue and enduring allure, the ruby has captivated civilizations for centuries. As a variety of the mineral corundum, the ruby’s color is primarily due to trace amounts of chromium, and its hardness ranks second only to diamond. This article explores the ruby’s gemological properties, its historical and symbolic importance, and its enduring place in jewelry and cultural traditions.
Historical Significance and Lore
The ruby has long been revered across cultures for its deep red color, which has been associated with vitality, passion, and power. Ancient Indian texts refer to the ruby as the “king of precious stones,” a title that underscores its rarity and esteemed status in the world of gemstones. In medieval Europe, rubies were believed to bestow health, wisdom, and success in love. These beliefs, rooted in centuries of tradition, have contributed to the ruby's enduring mystique.
Cultural Beliefs and Symbolism
Across different cultures, the ruby has held various symbolic meanings. In ancient times, Burmese warriors carried rubies into battle, believing the gemstone would grant them invincibility. In India, the ruby was linked to the life force and was thought to enhance youthful energy and vitality. Some historical accounts suggest that rubies were believed to predict misfortune or danger, and others claimed the gem could cure inflammatory diseases and soothe anger.
The ruby's vibrant red color has often been associated with the heart and life force. This symbolism has made the ruby a popular choice for romantic and sentimental jewelry. As a July birthstone, the ruby is seen as a representation of deep emotions, love, and energy. In some traditions, the ruby is also linked to the zodiac sign of Cancer, which is ruled by the Moon.
Geological Formation and Sources
Rubies are formed deep within the Earth's crust under intense heat and pressure. They belong to the corundum family, which also includes sapphires. The key distinguishing factor between rubies and sapphires is the presence of chromium, which gives rubies their characteristic red color. The more chromium present in the corundum, the stronger the red hue.
Key Mining Locations
Rubies are found in various parts of the world, though some regions are particularly renowned for producing high-quality stones. The finest rubies, especially those with the coveted "pigeon's blood" color, are often sourced from Myanmar (formerly Burma). Other notable ruby-producing regions include:
- Myanmar (Burma): Known for producing some of the most valuable and beautiful rubies, particularly the "pigeon's blood" variety.
- Madagascar: A major source of rubies in the modern era, with significant deposits discovered in the late 20th century.
- Sri Lanka: Produces high-quality rubies and is known for its long history of gemstone mining.
- Afghanistan, Tanzania, and Thailand: These countries also contribute to the global ruby market, each with its own unique geological characteristics and ruby qualities.
The ruby’s formation and distribution are influenced by tectonic activity and mineral composition. The gemstone is often found in metamorphic rocks such as marble and basalt, and its formation is closely tied to the geological history of the regions where it is mined.
Gemological Properties
The ruby is one of the hardest gemstones, second only to the diamond on the Mohs scale of mineral hardness. This hardness makes it durable and suitable for use in a wide range of jewelry, including rings and bracelets. However, despite its hardness, rubies can still be damaged if exposed to harsh conditions or improper handling.

Color and Value
The value of a ruby is largely determined by its color, clarity, cut, and carat weight. The most valuable rubies are those with a deep red color, excellent clarity, and a well-executed cut that maximizes the stone’s brilliance. Larger rubies are rarer and can command significantly higher prices. For example, a ruby weighing more than 5 carats in the "pigeon's blood" color is extremely rare and highly valuable.

Modern interpretations of the ruby’s metaphysical properties include its association with the heart chakra. It is believed to promote emotional healing, enhance love and passion, and encourage a deep connection with others. Some practitioners also use rubies in meditation to stimulate energy flow and enhance spiritual awareness.
Care and Cleaning
Due to its hardness and durability, the ruby is a relatively easy gemstone to care for. However, proper care is essential to maintain its beauty and longevity. Rubies should be cleaned using a mild detergent and warm water, followed by a gentle scrub with a soft brush. After cleaning, the gemstone should be rinsed thoroughly and dried with a soft cloth.
Avoiding Damage
While rubies are durable, they can still be damaged if exposed to harsh conditions. It is important to avoid exposing rubies to:
- Harsh chemicals: These can damage the gemstone’s surface and affect its color.
- Extreme temperatures: Sudden temperature changes can cause stress and potentially lead to cracks.
- Hard impacts: Although rubies are hard, they can still chip or crack if struck with enough force.
For jewelry containing rubies, it is recommended to store the pieces separately to prevent scratches and damage. Avoid wearing ruby jewelry during activities that may expose the gemstone to rough handling or chemicals.
