History and Lore
Ruby’s historical significance is as vibrant as its color. The name “ruby” comes from the Latin word ruber, meaning “red,” a color long associated with life, love, and strength. In ancient times, ruby was considered one of the most powerful and valuable gemstones. In India, ruby was revered as the “king of precious stones” for its rarity, hardness, and beauty. It was believed to possess mystical powers that could bring divine favor, prosperity, and protection.
Ancient Chinese emperors wore rubies believing they contained the life force of the universe. These rulers saw rubies as symbols of health, vitality, and spiritual power. In the same way, Burmese warriors believed that wearing rubies in battle would make them invincible. These cultural associations underscore the deep spiritual and symbolic value ruby has carried for centuries.
In medieval Europe, ruby was often set into royal crowns and jewelry as a symbol of power and divine right. It was also believed to have protective properties, with some sources suggesting that it could predict misfortune or danger. Others claimed it could cure inflammatory diseases and soothe anger, reinforcing its reputation as a stone of emotional and physical well-being.
As a birthstone for July 12, ruby continues to be a symbol of passion, vitality, and courage. Those born on this day are thought to inherit the ruby’s fiery energy and emotional intensity, making it a fitting representation of their inner strength and life force.
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 due to the presence of chromium, which replaces some of the aluminum atoms in the crystal lattice. The more chromium present, the stronger the red hue. A particularly desirable shade known as “pigeon’s blood” ruby is characterized by a deep red with a subtle hint of purple. This color is highly prized in the gemstone trade.
Geologically, ruby forms under high-pressure and high-temperature conditions deep within the Earth’s crust. These conditions allow corundum to crystallize, and the presence of chromium gives the stone its signature red color. Ruby is typically found in metamorphic rocks, often in association with marble and other calcium-rich minerals.
Historically, the most famous ruby deposits were found in Burma (now Myanmar), which was long known for producing some of the finest rubies in the world. Other notable sources include Thailand, Sri Lanka, India, and more recently, Mozambique. Each of these regions produces rubies with slightly different characteristics, influenced by the local geology and trace elements.
The durability of ruby is one of its most notable properties. With a hardness of 9 on the Mohs scale, ruby is second only to diamond in terms of toughness. This makes it suitable for everyday wear and ideal for setting into rings, bracelets, and necklaces.
Gemological Properties
Understanding the gemological properties of ruby is essential for appreciating its beauty and value. Here is an overview of the key characteristics that define this remarkable gemstone:
| Property | Description |
|---|---|
| Chemical Formula | Al₂O₃ |
| Crystal System | Hexagonal |
| Hardness (Mohs Scale) | 9 |
| Refractive Index | 1.76–1.78 |
| Specific Gravity | 3.95–4.10 |
| Color | Deep red with a violet or purple undertone in the finest specimens (pigeon’s blood) |

Ruby is typically cut into round brilliant or oval shapes to maximize its color and brilliance. The ideal cut enhances the ruby’s deep red hue while minimizing the appearance of inclusions. High-quality rubies with minimal inclusions and a strong red color are the most valuable.
It is important to note that many rubies on the market today have been heat-treated to improve their color and clarity. While this is a common and accepted practice in the gem trade, it can affect the stone’s value and should be disclosed when purchasing ruby jewelry.
Symbolism and Metaphysical Beliefs
Ruby has long been associated with powerful symbolism and metaphysical properties. In many cultures, it is seen as a stone of vitality and life force. Its deep red color is often linked to the heart chakra, representing love, courage, and emotional strength.
In ancient India, ruby was considered a sacred gemstone believed to bring prosperity and divine favor. It was often worn by royalty and spiritual leaders as a symbol of power and protection. In some traditions, ruby was thought to enhance one’s ability to make wise decisions and to inspire confidence and leadership.

Some believe that ruby can help overcome fear, anxiety, and emotional pain, making it a valuable stone for those seeking emotional healing and balance.
In modern metaphysical practices, ruby is still revered for its energizing properties. It is said to stimulate the lower chakras, promoting a sense of security, passion, and motivation.

Care and Cleaning
Given its high hardness and durability, ruby is a relatively easy gemstone to care for. However, proper cleaning and maintenance are essential to preserving its beauty and integrity over time.
Cleaning
Ruby can be cleaned using warm, soapy water and a soft brush. A mild dish soap or a commercial jewelry cleaner is typically sufficient for removing dirt and debris. Avoid using harsh chemicals, as they can potentially damage the gemstone or the metal setting.
Ultrasonic cleaners can be used for ruby jewelry, but it is important to ensure that the gemstone has no fractures or surface-reaching inclusions, as these can be exacerbated by the vibrations. Steam cleaners are generally not recommended for ruby due to the potential for thermal shock and water trapped in fissures.
Storage
To prevent scratches and damage, ruby jewelry should be stored separately from other gemstones, especially softer ones like emerald, opal, or pearl. A soft pouch or a lined jewelry box is ideal for storing ruby pieces.
Handling
Avoid exposing ruby jewelry to high-impact activities or environments where it could be subjected to extreme temperatures or chemical exposure. While ruby is very durable, it can still be chipped or fractured if struck with sufficient force.
Regular inspections by a professional jeweler can help ensure that the ruby remains secure in its setting and that any signs of wear or damage are addressed promptly.
