History and Lore
Ancient Reverence and Symbolism
The ruby has been cherished for thousands of years, with ancient cultures attributing powerful properties to the stone. In ancient India, ruby was known as Ratnaraj, meaning “King of Gemstones.” This title reflects the gem’s esteemed status and its association with royalty and divine power. Indian jewelers and spiritual leaders believed that rubies could bestow good fortune, protection, and vitality to their wearers. The gemstone was often incorporated into royal regalia and sacred objects, symbolizing the life force and energy of the sun.
In medieval Europe, rubies were thought to possess healing and protective qualities. They were believed to bring health, wisdom, and success in love. Warriors wore rubies into battle, convinced that the gemstone would grant them courage and invincibility. During the Renaissance, ruby jewelry became a symbol of nobility and status, often adorning the crowns and regalia of monarchs across Europe.
In China, ruby was considered a symbol of prosperity and good luck. It was used in imperial jewelry and was believed to bring harmony and happiness to the household. Chinese jade carvers and gemologists revered ruby for its vibrant red color, associating it with vitality and the warmth of the sun.
Evolution as a Birthstone
The designation of ruby as a birthstone for July is a more modern development, but its roots can be traced back to ancient traditions. The association of ruby with July likely stems from its symbolic connection with summer and vitality. As one of the four precious gemstones, ruby has long been used in jewelry to commemorate important life events and to bestow blessings upon the wearer.
In the 20th century, the American National Association of Jewelers (now the Jewelers of America) officially recognized ruby as the July birthstone in 1912. This designation was based on historical and cultural significance, as well as the gemstone’s enduring popularity in jewelry design. Ruby’s fiery red color and exceptional hardness made it an ideal choice for a birthstone that could endure daily wear while retaining its beauty.
For those born on July 26th, ruby holds a special place as their personal birthstone. It is seen as a reflection of their vibrant and dynamic nature, embodying qualities such as passion, courage, and determination.

Geological Formation and Sources
Chemical Composition and Formation
Ruby is a variety of the mineral corundum, which has the chemical formula Al₂O₃. Pure corundum is colorless, but trace amounts of other elements can cause it to take on different hues. In the case of ruby, the red color is due to the presence of chromium (Cr) or, less commonly, vanadium (V). The more chromium present in the crystal structure, the deeper the red color.
Ruby forms deep within the Earth’s crust under high-pressure and high-temperature conditions. It typically occurs in metamorphic rocks, such as marble, and is often found in association with other minerals like sapphire, zircon, and spinel. The process of ruby formation can take millions of years, during which the mineral is subjected to extreme geological forces that shape and color it.
The clarity and color of a ruby are influenced by various factors, including the presence of inclusions, the intensity of the red hue, and the overall cut and polish of the stone. High-quality rubies are those that exhibit a deep, vivid red with a slight purple overtone, known in the trade as "pigeon’s blood." These stones are considered the most valuable and are highly sought after by collectors and jewelers.
Major Sources of Ruby
Ruby is found in several regions around the world, each producing stones with unique characteristics. The most famous and historically significant source of ruby is Myanmar (formerly Burma), particularly the Mogok region. Burmese rubies are renowned for their rich red color and exceptional quality, making them some of the most valuable gemstones in the world. The presence of chromium in these stones gives them their intense red hue, while the geological conditions in Myanmar contribute to their clarity and brilliance.
Other notable sources of ruby include Thailand, Sri Lanka, Tanzania, and Madagascar. Thai rubies are typically lighter in color and often have a more orangy hue due to the influence of iron in their composition. Sri Lankan rubies are known for their vibrant red color and are often found in alluvial deposits, where they have been naturally rounded and polished by water over time.
Tanzanian rubies, particularly those from the Winza矿区 (a mining area in Tanzania), have gained popularity in recent years for their deep red color and high quality. These stones are often compared to Burmese rubies and are considered a significant source in the global ruby market. Madagascar has also emerged as a major ruby producer, with stones from the Ilakaka region exhibiting a wide range of colors and qualities.
The availability of ruby from different sources has allowed for a diverse supply of the gemstone, catering to both high-end collectors and everyday jewelry consumers. However, the most valuable rubies continue to be those from Myanmar, due to their exceptional color and historical significance.
Gemological Properties
Physical and Optical Characteristics
Ruby is one of the hardest natural gemstones, ranking 9 out of 10 on the Mohs Hardness Scale. This makes it highly durable and suitable for everyday wear in jewelry. Its hardness is second only to diamond, which ranks at 10. This durability is due to the strong atomic bonds within the corundum structure, which resist scratching and abrasion.
The refractive index of ruby is between 1.76 and 1.78, which gives it a brilliant luster when cut and polished. The gemstone exhibits strong pleochroism, meaning it can display different colors when viewed from different angles. In some cases, a ruby may appear more orange or purple depending on the light source and the angle of observation.
Ruby is also known for its high dispersion, or fire, which refers to the way it splits light into different colors. While not as intense as in diamond, the dispersion in ruby contributes to its overall brilliance and visual appeal.
Color and Quality Factors
The most important factor in determining the value of a ruby is its color. The ideal ruby color is a deep red with a slight purple overtone, often described as "pigeon’s blood." This color is highly prized and commands the highest prices in the gemstone market. The presence of chromium in the crystal structure is responsible for this color, with higher concentrations of chromium leading to a more intense red.
Other factors that influence the value of a ruby include clarity, cut, and carat weight. High-quality rubies are typically free of visible inclusions, though some natural inclusions are expected and can even be used to identify the origin of the stone. The cut of a ruby also plays a crucial role in its appearance, as a well-cut stone will maximize its brilliance and color.
Carat weight is another important factor, as larger rubies are rarer and more valuable. However, the value of a ruby is not simply a function of its size but also its color, clarity, and overall quality. A small, high-quality ruby can be more valuable than a larger stone with a less intense color or visible inclusions.

Care and Cleaning
Daily Maintenance
Given its high hardness and durability, ruby is well-suited for everyday wear. However, like all gemstones, it requires proper care to maintain its beauty and longevity. To keep a ruby looking its best, it is important to avoid exposing it to harsh chemicals, extreme temperatures, or physical impacts.
Ruby jewelry should be cleaned regularly to remove dirt, oils, and other debris that can dull its brilliance. A simple cleaning solution of warm water and mild dish soap is typically sufficient for most ruby jewelry. The gemstone can be gently scrubbed with a soft-bristled toothbrush and then rinsed thoroughly with lukewarm water. After cleaning, the jewelry should be dried with a soft cloth to prevent water spots.
For more thorough cleaning, a professional ultrasonic cleaner can be used. However, it is important to check with a jeweler first, as some ruby treatments, such as oiling or glass-filling, may be sensitive to ultrasonic cleaning. In general, untreated rubies are safe to clean with ultrasonic methods.
Storage and Handling
To prevent damage, ruby jewelry should be stored separately from other gemstones, especially those with lower hardness. This helps to prevent scratches and abrasions that can occur when harder gemstones come into contact with softer ones. It is also advisable to store ruby jewelry in a soft cloth or jewelry box to prevent exposure to dust and other environmental factors.
When wearing ruby jewelry, it is important to avoid activities that may subject the gemstone to impact or pressure. While ruby is one of the hardest gemstones, it can still be damaged if struck with sufficient force. It is also advisable to remove ruby jewelry before engaging in activities such as sports, gardening, or cleaning, where the gemstone may be exposed to harsh chemicals or physical stress.
