As a birthstone, it carries a legacy of symbolism tied to love, passion, and protection, making it a meaningful and elegant choice for jewelry and gifting. In this article, we delve into the ruby’s storied past, its physical and chemical properties, its role in jewelry design, and the care it requires to maintain its brilliance.
History and Lore
The ruby has long been regarded as one of the most precious gemstones in the world, with a history that spans thousands of years. Its deep red color has been associated with vitality, power, and even the divine. Ancient Sanskrit writings and biblical texts both mention rubies, describing them as the most cherished of all gemstones. In many ancient cultures, the ruby was believed to be a symbol of the sun and was thought to grant the wearer courage, strength, and good fortune. It was often worn by kings and emperors as a symbol of their authority and was considered a talisman of protection.
The ruby’s allure has not diminished over time; in fact, it has only grown. As the birthstone for July, it has become a cherished symbol for those born in this month. The name “ruby” comes from the Latin word ruber, meaning red, and it has remained a popular choice for jewelry due to its striking color and durability. In modern times, the ruby is often associated with love and passion, making it a fitting gift for romantic milestones such as anniversaries or engagements.
The ruby has also played a role in various myths and legends. Some cultures believed that the ruby could protect the wearer from danger and illness, while others thought it could enhance spiritual wisdom and energy. In medieval Europe, rubies were believed to be the “king of precious stones,” and they were often used in royal regalia and religious artifacts. These historical associations have contributed to the ruby’s enduring appeal and its continued use in high-quality jewelry today.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is also the source of sapphires. What distinguishes a ruby from a sapphire is the presence of chromium, which gives it its signature red color. The intensity of the red hue can vary depending on the concentration of chromium and the presence of other trace elements. The finest rubies exhibit a deep, vivid red known as "pigeon’s blood," a term often used in the gem trade to describe the most desirable color.
Rubies are formed deep within the Earth’s crust under high pressure and temperature conditions. They are typically found in metamorphic rocks and are often associated with marble formations. The process of formation can take millions of years, resulting in gemstones that are not only beautiful but also incredibly durable. Rubies rank between 8 and 9 on the Mohs scale of hardness, making them highly resistant to scratches and damage, which is one of the reasons they are so well-suited for use in jewelry.
The most well-known sources of rubies include Myanmar (formerly Burma), which is famous for producing some of the finest rubies in the world. Other notable sources include Thailand, Sri Lanka, Afghanistan, and Tanzania. In recent years, rubies have also been found in parts of Mozambique, where new deposits have emerged. These rubies are known for their vibrant colors and high quality. The availability of rubies from various regions has contributed to their widespread use in jewelry and their popularity as a birthstone.
Gemological Properties
Understanding the gemological properties of the ruby is essential for appreciating its value and beauty. The ruby’s chemical composition is aluminum oxide (Al₂O₃), with chromium as the primary element responsible for its red color. This composition gives the ruby its hardness and durability, making it an excellent choice for everyday wear in jewelry. In addition to its hardness, the ruby has a refractive index of approximately 1.76 to 1.78, which contributes to its brilliance and sparkle when cut and polished.
The cut of a ruby plays a crucial role in its appearance. The most common cuts for rubies include the emerald cut, the round brilliant cut, and the cushion cut. Each cut is designed to enhance the stone’s color and brilliance while minimizing any inclusions or imperfections. The clarity of a ruby can vary, with the most valuable stones being those that are eye-clean, meaning they have no visible inclusions to the naked eye. However, even rubies with minor inclusions can be highly desirable if they exhibit a strong color and well-executed cut.
The weight of a ruby is measured in carats, with larger stones being rarer and more valuable. High-quality rubies over one carat are particularly sought after and can command significant prices in the market. The combination of the ruby’s hardness, color, and clarity makes it one of the most desirable gemstones for use in fine jewelry, especially for rings, earrings, and pendants.
Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been imbued with various symbolic meanings and metaphysical properties. In ancient times, it was believed to be a protective stone that could ward off evil spirits and bring good fortune to the wearer. In some cultures, it was thought to enhance the wearer’s vitality and energy, making it a popular stone for warriors and leaders. In medieval Europe, rubies were associated with the heart and were believed to promote love and passion. They were often used in romantic jewelry and were given as gifts to express deep affection.
Modern metaphysical beliefs continue to attribute powerful properties to the ruby. It is often referred to as the “stone of passion,” believed to stimulate the heart chakra and encourage emotional and physical vitality. Some practitioners use rubies in meditation to enhance their energy levels and to encourage courage and self-confidence. In crystal healing, the ruby is thought to have a warming effect, helping to alleviate fatigue and stress. It is also believed to enhance spiritual awareness and to provide protection from negative influences.
The ruby’s symbolic associations have made it a popular choice for jewelry that is given as a gift for important life events. It is often used in engagement rings, anniversary gifts, and as a symbol of personal achievement. Its rich red color and enduring beauty make it a meaningful and elegant way to commemorate love, success, and milestones in life.
Care and Cleaning
Proper care is essential to preserving the beauty and longevity of ruby jewelry. While rubies are durable, they can still be damaged by harsh chemicals, extreme temperatures, or physical impact. To maintain the ruby’s brilliance, it is important to clean it regularly and store it properly.
To clean a ruby, it is best to use a mild soap and warm water. A soft brush, such as a toothbrush, can be used to gently scrub the surface of the stone and remove any dirt or debris. Avoid using ultrasonic cleaners or steam cleaners, as these can cause damage to the ruby or its setting. It is also important to avoid exposing the ruby to harsh chemicals such as bleach, ammonia, or acidic substances, which can dull its luster.
When not in use, ruby jewelry should be stored in a soft, protective pouch or in a jewelry box to prevent scratches and other damage. It is advisable to store rubies separately from other gemstones to avoid any potential contact that could lead to abrasion. If the ruby is set in a piece of jewelry with other stones, it is important to ensure that the setting is secure and that the ruby is not loose or damaged.
Regular inspections by a professional jeweler are also recommended to check for any signs of wear or damage. A jeweler can assess the condition of the ruby and its setting and make any necessary repairs to ensure that the piece remains in excellent condition.

The ruby, as the birthstone for July, is a gemstone of remarkable beauty, history, and significance. Its deep red color, symbolic power, and enduring appeal make it a popular choice for jewelry and gifting. Whether used in classic designs such as solitaire pendants or more intricate creations featuring multiple gemstones, the ruby continues to captivate and inspire.
