The July birthstone, ruby, is renowned for its captivating red hue and has been treasured for millennia. Often called the “King of Colored Stones,” this gemstone embodies passion, protection, and prosperity. This article delves into the history, geological origins, gemological properties, symbolism, and care of the ruby, offering a comprehensive overview of this remarkable gem.
History and Lore
Rubies boast a rich history interwoven with ancient cultures and beliefs. In ancient India, the ruby was referred to as the “king of precious stones,” valued for its rarity, beauty, and perceived mystical powers. It was associated with the life force, symbolized by blood, and believed to imbue jewelry wearers with youthful energy. Burmese warriors historically carried rubies into battle, convinced the stones rendered them invincible.
Medieval Europeans attributed a range of benefits to rubies, believing they conferred health, wisdom, wealth, and success in love. The gem’s significance is also evident in religious texts, appearing explicitly four times in the Bible, highlighting its ancient reverence. Throughout history, royal families worldwide have prized rubies as emblems of power and wealth. The tradition of gifting rubies for the 15th and 40th wedding anniversaries further underscores its enduring symbolism. The concept of birthstones themselves evolved through the Middle Ages, linking gemstones to specific months or zodiac signs, with standardization occurring in the 20th century through organizations like the American National Retail Jewelers Association.
Geological Formation and Sources
Ruby is a variety of the mineral corundum, the same species that creates sapphires. The distinctive red color arises from trace amounts of chromium present during the gem’s formation. The intensity of the red is directly proportional to the amount of chromium – the more chromium, the deeper and more vibrant the hue.
While specific mining locations are not extensively detailed in the provided sources, the text highlights the historical importance of rubies from Burma (now Myanmar). The finest ruby color, known as “pigeon’s blood,” is a deep red with a hint of purple, a shade highly sought after in the trade.
Gemological Properties
Ruby’s value is determined by a combination of factors: color, cut, clarity, and carat weight. Color is paramount, with the “pigeon’s blood” shade commanding the highest prices. Clarity also plays a crucial role; while flawless rubies are rare, the presence of needle-like rutile inclusions can sometimes indicate that the stone has undergone treatment to enhance its appearance.
Ruby is exceptionally durable, ranking second only to diamond in hardness. This durability makes it well-suited for everyday wear. Technically, ruby and sapphire are both corundum, with ruby defined as the red variety. Rubies can exhibit orange or pink undertones, though the purest red shades are the most valuable. The world’s most valuable ruby sold at auction, the Estrela de Fura, achieved a price exceeding $34.8 million.
Here's a table summarizing key gemological properties:
| Property | Description |

| Mineral | Corundum |
| Color | Red (varying shades) |
| Hardness (Mohs) | 9 |
| Luster | Adamantine |
| Transparency | Transparent to Translucent |
| Chemical Formula | Al₂O₃ |
| Key Element | Chromium (responsible for red color) |
Symbolism and Metaphysical Beliefs
Throughout history, rubies have been imbued with profound symbolic meaning. They have long been associated with physicality and strength, favored by warriors who believed they enhanced stamina and provided protection. Beyond physical prowess, rubies were thought to calm anger and facilitate successful navigation of passionate social interactions.
The symbolism extends to the realm of love and passion, reflected in the gem’s association with the month of July and its Latin name, ruber, meaning red. Ancient beliefs also attributed healing properties to rubies, with some claiming they could cure inflammatory diseases. The gem was believed to offer protection against misfortune and danger, acting as a talisman for its wearer.
