History and Lore
Ruby has a long and storied history, with records of its use stretching back to ancient civilizations. In Sanskrit, ruby is referred to as Ratnaraj, meaning “king of gemstones,” a title that reflects its esteemed status. In ancient Hindu tradition, rubies were believed to possess divine properties and were often offered to deities such as Krishna in hopes of ensuring prosperity and power.
In Burma (now Myanmar), where some of the finest rubies in the world have been mined for centuries, the gemstone was thought to bring invincibility in battle. Warriors wore ruby-studded jewelry to protect themselves and enhance their courage. These beliefs highlight the deep cultural reverence for ruby as a stone of strength and vitality.
Throughout history, ruby has been treasured by royalty and the elite across various civilizations. From the courts of ancient India and China to medieval Europe, ruby was a symbol of power and divine favor. Kings and queens adorned themselves with ruby jewelry, and the gemstone was often incorporated into royal regalia and crowns. The association of ruby with leadership and nobility further solidified its status as a gem of great importance.
The official designation of ruby as the July birthstone is relatively modern. In 1912, the Jewelers of America adopted ruby as the primary birthstone for the month of July, a decision that has since been widely accepted and recognized. Prior to this, both onyx and turquoise were also considered appropriate birthstones for July. However, ruby’s deep red color, symbolic meaning, and geological durability made it the natural choice to represent the heart of summer.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, a crystalline form of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties is the presence of trace amounts of chromium, which gives the gemstone its characteristic red color. Chromium replaces some of the aluminum atoms in the crystal lattice, causing the absorption of certain wavelengths of light and the transmission of red light. The intensity of the red color can vary depending on the concentration of chromium and the presence of other trace elements.
Ruby’s formation is a result of high-pressure and high-temperature conditions deep within the Earth’s crust. It typically forms in metamorphic rocks, specifically in environments where aluminum-rich minerals are subjected to intense heat and pressure over millions of years. These conditions allow the corundum to crystallize and incorporate trace elements that determine the gemstone’s color.
Myanmar is the most historically significant source of ruby, with the Mogok Stone Tract being particularly renowned for producing some of the finest examples of the gemstone. The rubies from this region are often referred to as “pigeon blood” rubies due to their intense, vibrant red color with a slight blue undertone. Other notable ruby-producing countries include Thailand, Cambodia, Vietnam, Tanzania, Afghanistan, and parts of India and Sri Lanka. Each region produces rubies with slightly different characteristics, influenced by local geological conditions.
The durability of ruby is one of its defining features. With a hardness of 9 on the Mohs Hardness Scale, ruby is second only to diamond in terms of resistance to scratching and abrasion. This makes it an excellent choice for everyday jewelry, as it can withstand regular wear and tear. Additionally, ruby is resistant to common types of damage, such as chipping or cracking, although it may have cleavage planes along which it can split if struck with sufficient force.
Gemological Properties
Ruby is one of the most valuable and sought-after gemstones in the world, and its desirability is due in large part to its exceptional gemological properties. Below is a summary of the key characteristics of ruby, as outlined in the provided sources:
| Property | Description |
|---|---|
| Chemical Formula | Al₂O₃ (Aluminum Oxide) |
| Crystal System | Hexagonal |
| Hardness (Mohs Scale) | 9 |
| Refractive Index | 1.76–1.78 |
| Color | Deep red (caused by chromium) |
| Luster | Vitreous (glassy) |
| Cleavage | Slightly imperfect in one direction |
| Transparency | Transparent to translucent |
| Inclusions | Common (e.g., rutile needles, “silk” inclusions) |
| Common Cuts | Round, oval, cushion, emerald, and pear-shaped cuts |
| Treatment | Heat treatment is common to enhance color and clarity |
The color of ruby is the most critical factor in determining its value. The most prized rubies exhibit a deep, saturated red with a slight blue undertone — a color often described as “pigeon blood.” This term, though not recognized in scientific gemology, is widely used in the trade to describe the most beautiful and valuable rubies.
Clarity is also an important factor in evaluating ruby. While inclusions are common and often accepted as natural features of the gemstone, too many or too large inclusions can detract from its beauty and value. However, certain inclusions, such as rutile needles, can enhance the appearance of ruby by creating a desirable “silk” effect that softens the light and gives the stone a velvety appearance.
Cuts are chosen based on the shape and quality of the rough crystal. Round and oval cuts are the most popular, but ruby can also be found in cushion, emerald, and pear-shaped cuts. The goal of the cutting process is to maximize the gemstone’s brilliance and color while minimizing the visibility of inclusions.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful and positive energies, and it has been revered across cultures for its symbolic meaning. The deep red color of ruby is often linked to blood, fire, and life force, making it a symbol of vitality, passion, and strength. In ancient times, ruby was believed to bring good fortune, protect against harm, and enhance the wearer’s courage and confidence.
In medieval Europe, ruby was considered a protective gemstone and was often set into pendants or rings to ward off illness and misfortune. It was also believed to promote love and strengthen relationships. In some traditions, ruby was used in talismans and amulets to ensure success in battle and to inspire bravery in warriors.
In the East, ruby has been regarded as a stone of spiritual significance. In Hindu and Buddhist traditions, ruby is believed to promote wisdom, clarity, and emotional balance. It is also associated with the heart chakra and is said to enhance love, compassion, and emotional healing.
Modern metaphysical beliefs continue to attribute ruby with powerful properties. It is considered a stone of passion and vitality, making it especially beneficial for those seeking motivation, confidence, and emotional strength. Ruby is also believed to stimulate creativity, enhance leadership qualities, and encourage a deep connection with one’s inner fire.
Care and Cleaning
Due to its high hardness and durability, ruby is well-suited for daily wear. However, like all gemstones, it requires proper care to maintain its brilliance and longevity. The following guidelines are recommended for cleaning and preserving ruby jewelry:
Cleaning Methods:
Ruby can be cleaned with mild soap and warm water. Use a soft brush to gently remove dirt and debris from the surface and crevices of the gemstone. Avoid using harsh chemicals or abrasive materials, as these can damage the gemstone or the metal setting.Ultrasonic Cleaners:
Ruby is generally safe to clean using ultrasonic cleaners, as its hardness and lack of cleavage make it resistant to damage from vibrations. However, if the ruby contains inclusions that could trap water or if it has been treated with glass or other coatings, ultrasonic cleaning should be avoided.Steam Cleaning:
Steam cleaning is another effective method for cleaning ruby. It is gentle and helps to dissolve dirt and grime without causing damage to the gemstone.Storage:
To prevent scratches and damage, ruby should be stored separately from harder gemstones such as diamonds. It can be kept in a soft-lined jewelry box or wrapped in a soft cloth to protect it from abrasion.Avoiding Extreme Conditions:
Although ruby is highly durable, it should be protected from sudden temperature changes and exposure to high heat. Prolonged exposure to direct sunlight or artificial heat sources can cause the gemstone to fade or become brittle.Avoiding Chemical Exposure:
Ruby should not be exposed to harsh chemicals such as bleach, ammonia, or strong acids, as these can damage the surface of the gemstone. When using household cleaners or perfumes, it is advisable to remove ruby jewelry first.Professional Cleaning and Inspection:
Periodically, ruby jewelry should be inspected by a professional jeweler to ensure that the gemstone is securely set and that the metal setting is in good condition. This is especially important for rings and other pieces that are worn frequently.
By following these care and cleaning guidelines, ruby jewelry can retain its beauty and value for many years. Proper maintenance not only preserves the appearance of the gemstone but also ensures its durability and longevity.
