History and Lore
The ruby has been treasured for millennia, with references dating back to ancient civilizations in India, China, and Europe. Known for its vibrant red color, the ruby was often associated with the life force and vitality of the human body. Ancient warriors believed that wearing a ruby could bring them courage and protect them in battle. The gemstone was also believed to bring prosperity and ward off evil.
In many cultures, the ruby was considered a stone of the heart and the soul. Its red color, reminiscent of blood and fire, made it a powerful symbol of life and passion. Royal families across the world have historically used rubies in their regalia and jewelry, signifying power and divine favor.

The name "ruby" is derived from the Latin word "ruber," meaning red. This name is a fitting tribute to the gemstone’s vibrant hue, which has captivated people for centuries. The ruby’s historical significance and enduring appeal make it a fitting birthstone for those born on July 1st.
Geological Formation and Sources
The ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties is the presence of chromium, which imparts its characteristic red color. The intensity of the red hue depends on the concentration of chromium within the gemstone.
Ruby forms under high-pressure and high-temperature conditions in metamorphic rocks and alluvial deposits. The most prized rubies are typically found in alluvial deposits, where they are weathered from their original host rock and transported by water. These deposits often yield gemstones of high quality and clarity.
The primary sources of ruby include:
- Myanmar (Burma): Known for producing some of the finest rubies in the world, particularly the "Pigeon’s Blood" ruby, which is highly valued for its intense red color and exceptional clarity.
- Thailand: Although the quality of rubies from Thailand is often lower than those from Myanmar, the country has a long history of ruby trade and processing.
- India: Historical sources of ruby, with significant deposits in the Kollur mine in Golconda, which was once the most famous source of rubies.
- Sri Lanka: Known for producing a range of corundum gemstones, including rubies with a slightly different hue compared to those from Myanmar.
- Vietnam: A relatively new source of ruby, with high-quality stones being discovered in the region.
The formation and sourcing of ruby highlight its geological rarity and the conditions necessary to produce such a precious gemstone. These factors contribute to its high value and enduring appeal.
Ruby in the July Birthstone Calendar
While the ruby is the official birthstone for the entire month of July, those born on July 1st are particularly associated with this gemstone. The ruby's energy is described as bold and heart-driven, resonating with individuals who are passionate and confident.
In some traditions, the first half of July (July 1st to July 15th) is especially linked to the ruby. This period is considered a time of vitality and emotional resilience, with the ruby helping to enhance these qualities. Complementary gemstones, such as carnelian and onyx, are also recommended for those born during this period to provide additional support in creativity and grounding.
For those born later in the month, from July 16th to July 31st, the ruby remains a dominant birthstone, but alternative gemstones like alexandrite, sardonyx, and onyx are also considered to promote balance, clarity, and spiritual evolution. These stones are believed to support the transition from the nurturing energy of Cancer to the bold, confident energy of Leo.
The personalization of July birthstones based on birth dates reflects a deeper understanding of the gemstone's properties and their alignment with individual energies. This approach enhances the emotional and symbolic significance of the birthstone for those born in July.
Gemological Properties
The ruby’s gemological properties contribute to its status as one of the most valuable and sought-after gemstones. Its physical and optical characteristics make it a durable and beautiful stone that can be used in a wide range of jewelry designs.
Chemical Composition and Hardness
As a variety of corundum, the ruby is composed primarily of aluminum oxide (Al₂O₃). The red color of ruby is due to the presence of chromium, which replaces some of the aluminum atoms in the crystal lattice. The concentration of chromium determines the intensity of the red hue, with higher concentrations resulting in a more vivid color.
The ruby ranks 9 on the Mohs Hardness Scale, making it one of the hardest gemstones after diamond. This high hardness allows the ruby to resist scratches and abrasions, making it ideal for everyday wear. The durability of ruby ensures that jewelry pieces featuring this gemstone can be passed down through generations without significant damage.
Color and Clarity
The most valuable rubies exhibit a deep, intense red color, often described as "Pigeon’s Blood." This term refers to a specific shade of red with a slight blue undertone, which is considered the most desirable in the gemstone trade. The presence of inclusions, or internal characteristics, can affect the clarity of a ruby. While some inclusions are natural and can enhance the gemstone’s uniqueness, excessive inclusions can reduce its value and durability.
The cut of a ruby is also an important factor in its appearance and value. A well-cut ruby will maximize its brilliance and color, while a poorly cut stone may appear dull or lifeless. The most common cuts for ruby include the emerald cut, cushion cut, and round brilliant cut.
Refractive Index and Luster
Ruby has a refractive index of approximately 1.76 to 1.78, which contributes to its brilliance and fire. The gemstone exhibits a vitreous luster, which means it has a glass-like appearance. When properly cut and polished, ruby can display a high degree of sparkle and light return, making it a visually striking gemstone.
Other Physical Properties
In addition to its hardness and refractive index, ruby has other physical properties that make it a desirable gemstone. It has a specific gravity of around 4.00, which means it is relatively dense compared to other gemstones. Ruby also has a birefringence of 0.008 to 0.010, which can sometimes be observed as a doubling of facets when viewed through a loupe.
The ruby’s toughness is relatively good, although it can be affected by the presence of inclusions and the orientation of the gemstone. While ruby is highly resistant to scratching, it can be vulnerable to impact and cleavage, especially if it has existing fractures or inclusions.

Care and Cleaning
Given its high hardness and durability, ruby is a relatively easy gemstone to care for. However, it is still important to take proper care to preserve its beauty and longevity.
Cleaning
To clean ruby jewelry, a mild soap solution and a soft cloth or a soft-bristled brush can be used. Avoid using harsh chemicals or abrasive materials, as these can damage the gemstone or its setting. Ultrasonic cleaners can be used for ruby, but it is important to ensure that the gemstone does not have any inclusions or fractures that could be affected by the vibrations.
Steam cleaning is generally not recommended for ruby, as the high heat and pressure can potentially cause damage. If the gemstone has been treated or enhanced in any way, it is best to avoid using steam or ultrasonic cleaning methods.
Storage
When not in use, ruby jewelry should be stored in a soft, breathable fabric or a jewelry box to prevent scratches and damage. It is also a good idea to store ruby separately from other gemstones to avoid any potential abrasion.
Avoiding Damage
While ruby is a durable gemstone, it can still be vulnerable to impact and cleavage. It is important to avoid dropping the gemstone or subjecting it to sudden temperature changes. If the gemstone has inclusions or fractures, it is especially important to handle it with care.
Ruby is also sensitive to extreme heat, so it is best to avoid exposing it to high temperatures for extended periods. This includes avoiding prolonged exposure to direct sunlight or heat sources such as stoves or ovens.
