History and Lore
Ruby has a long and storied history that spans across civilizations and centuries. The name "ruby" comes from the Latin word ruber, meaning "red," a fitting tribute to its striking color. In ancient times, ruby was believed to bring protection, vitality, and good fortune. It was considered a symbol of the sun and was often associated with divine power and royalty.
In India, ruby has been revered since antiquity. Known as ratnaraj, which translates to "king of gemstones," ruby was believed to be a divine gift that could bring prosperity and happiness. It was commonly used in royal regalia and religious artifacts, reflecting its association with power and spiritual authority.
In medieval Europe, ruby was thought to have healing properties and was used in amulets to ward off disease and misfortune. It was also believed to promote love and passion, making it a popular gemstone for engagement rings and romantic gifts. The ruby's deep red color was often linked to the heart, symbolizing love, courage, and emotional strength.
Modern gemological institutions, such as the Gemological Institute of America (GIA) and the American Gem Society (AGS), recognize ruby as the official birthstone for July. While historical traditions may have included other stones like sardonyx or onyx as alternative July birthstones, ruby is now the sole officially recognized gemstone for the month. Its enduring popularity is due in part to its vibrant color and symbolic meaning, as well as its exceptional durability and beauty.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The deep red color of ruby is caused by the presence of chromium, which replaces some of the aluminum atoms in the crystal structure. The concentration of chromium determines the intensity of the red color, with the most valuable rubies exhibiting a rich, vibrant red hue often described as "pigeon's blood."
The formation of ruby requires specific geological conditions. Corundum, the mineral from which ruby is derived, is formed in metamorphic rocks under high pressure and temperature. Ruby can also be found in igneous rocks, particularly in basaltic and syenitic environments. These conditions allow for the incorporation of trace elements like chromium, which give ruby its distinctive color.
Ruby is found in various parts of the world, with the most famous sources being in Myanmar (formerly Burma), where the finest rubies have historically been mined. Other notable sources include Thailand, Sri Lanka, Madagascar, Afghanistan, and Tanzania. Each location produces rubies with slightly different characteristics, such as color tone and clarity.
In Myanmar, ruby is primarily found in the Mogok region, known for its "pigeon's blood" rubies. These rubies are highly prized for their intense red color and exceptional clarity. In Thailand, ruby is often treated to enhance its color, a practice that has been common for centuries. These treatments, such as heat treatment, can improve the gemstone's appearance and stability, making it more desirable in the market.
The mining and extraction of ruby are often challenging due to the remote and rugged locations where it is found. In some cases, ruby is discovered in alluvial deposits, where it has been eroded from its original rock and transported by water. These gemstones are often found in gravel beds and require careful sifting and sorting to locate.
The geological processes that create ruby are complex and require a deep understanding of mineralogy and geology. The rarity of high-quality ruby, combined with its vibrant color and durability, contributes to its status as one of the most valuable gemstones in the world.
Gemological Properties
Ruby is a remarkable gemstone not only for its beauty but also for its scientific properties. As a variety of corundum, ruby is composed of aluminum oxide (Al₂O₃) and is known for its hardness and brilliance. The following are some of the key gemological properties of ruby:
Color: Ruby is characterized by its deep red color, which is caused by the presence of chromium. The most valuable and desirable rubies exhibit a vibrant red color often referred to as "pigeon's blood." This term describes a stone that has a rich red color with a slight blue undertone, giving it a lively and intense appearance.
Hardness: On the Mohs Hardness Scale, ruby ranks at 9, making it one of the hardest gemstones, second only to diamond. This high hardness allows ruby to resist scratches and wear, making it suitable for everyday jewelry.
Luster: Ruby has a vitreous (glassy) luster, which contributes to its brilliance and fire. The gemstone's refractive index is approximately 1.76 to 1.78, and it exhibits strong double refraction, which can create a doubling effect when viewed through a loupe.
Clarity: Ruby can range from transparent to opaque, with the most valuable stones being transparent and free of inclusions. However, many rubies contain inclusions, which are natural characteristics that can affect their appearance and value. Some inclusions, such as rutile needles, are considered desirable as they can indicate the gemstone's origin.
Cut: Ruby is typically cut into various shapes, including round, oval, cushion, and princess cuts. The choice of cut depends on the gemstone's shape and inclusions. A well-cut ruby enhances its color and brilliance, making it more visually appealing.
Chemical Composition: As a form of corundum, ruby is composed of aluminum oxide (Al₂O₃) with trace amounts of chromium, which is responsible for its red color. The chemical stability of ruby makes it resistant to most acids and bases, although it can be affected by strong solvents and extreme heat.
These gemological properties make ruby a highly desirable gemstone for both jewelry and investment. Its combination of beauty, durability, and rarity ensures that ruby remains a popular choice for those seeking a meaningful and valuable gemstone.

Across different cultures and historical periods, it has been regarded as a gemstone of vitality, protection, and emotional strength. Its deep red color is often linked to the heart, making it a symbol of love, passion, and courage.
In ancient times, ruby was believed to have protective qualities and was often worn as an amulet to ward off evil and promote good health. It was also thought to enhance vitality and energy, making it a popular gemstone for warriors and leaders. In medieval Europe, ruby was associated with the sun and was believed to bring warmth and strength to the wearer.
In the context of crystal healing, ruby is considered a powerful stone that energizes the heart chakra and promotes emotional balance. It is believed to enhance self-confidence, stimulate motivation, and encourage a sense of purpose. Ruby is also thought to help clear emotional blockages and foster deeper connections with others.
Modern gemstone enthusiasts and spiritual practitioners continue to attribute various properties to ruby. Some believe that it can enhance creativity and inspire courage, making it a beneficial stone for those pursuing new goals or facing challenges.

These symbolic and metaphysical beliefs have contributed to ruby's enduring popularity as a gemstone. Whether worn for its beauty, its protective qualities, or its emotional significance, ruby remains a cherished and meaningful gemstone for those born in July and beyond.
Care and Cleaning
Due to its hardness and durability, ruby is a relatively easy gemstone to care for. However, proper maintenance is essential to ensure its continued beauty and longevity. The following are some guidelines for cleaning and preserving ruby jewelry:
Cleaning: Ruby can be cleaned using a solution of warm water and mild soap. A soft-bristled brush, such as a toothbrush, can be used to gently remove any buildup or debris. Avoid using harsh chemicals or abrasive materials, as these can damage the gemstone's surface.
Avoiding Heat and Sunlight: While ruby is generally stable, prolonged exposure to extreme heat or direct sunlight can cause it to lose its color or become brittle. It is advisable to store ruby jewelry in a cool, dark place when not in use.
Storage: To prevent scratches and damage, ruby jewelry should be stored separately from other gemstones, especially those that are softer. Soft pouches or jewelry boxes with individual compartments are ideal for storing ruby pieces.
