We will also examine its status as the primary birthstone for July, noting the alternative stones that have also been linked to this month. By synthesizing information from authoritative gemological sources, this guide provides a detailed, expert perspective for gemstone enthusiasts, jewelry buyers, and students of gemology.
History and Lore
The ruby’s history is as deep and compelling as its color. Revered across numerous cultures, it has long been a symbol of power, passion, and protection. In ancient India, the ruby was so esteemed that it was called the “king of precious stones,” a title acknowledging its rarity, exceptional hardness, beauty, and perceived mystical powers. This reverence is documented in ancient Indian texts, which highlight the stone’s esteemed status.
Throughout history, rubies were frequently worn by royalty and warriors. The gem’s association with leadership and courage solidified its position as a gemstone of high status. For instance, Burmese warriors believed that rubies made them invincible in battle, embedding the stone with a legacy of strength and fortitude. The deep red color of the ruby, reminiscent of blood, was often linked to the essence of life itself. In past centuries, some beliefs held that the ruby could predict misfortune or danger, while others claimed it could cure inflammatory diseases and soothe anger.
The journey to the ruby’s designation as the modern July birthstone involves a blend of ancient tradition and 20th-century standardization. While the ruby has been a prominent gemstone for millennia, its official status was formalized in the United States in 1912. In that year, the National Association of Jewelers (now the Jewelers of America) standardized birthstone lists, designating ruby as the primary July birthstone. This modern designation, however, exists alongside a longer, culturally-rooted history. Onyx, for example, has served as a recognized July birthstone for centuries, dating back to the 15th century. It held prominence in Jewish, Roman, and European traditions, celebrated for its striking appearance and perceived metaphysical properties. Despite the 1912 standardization, onyx has maintained its status as an acknowledged alternative, particularly favored for its modern aesthetic and grounding qualities. This duality reflects the evolving nature of birthstone traditions, which differ between modern designations and earlier, astrological systems.
Geological Formation and Sources
Rubies are a variety of the mineral corundum, a gem form of crystalline aluminum oxide (Al₂O₃). The red color of ruby is caused by trace amounts of the element chromium; the more chromium present, the stronger the red hue. Rubies are formed under specific geological conditions, typically found in limestone and gem gravels around the world. The presence of secondary shades like pink, orange, and violet can often indicate the country of origin.
While the provided sources do not list specific modern mining locations, they emphasize that rubies are found in various regions globally. The geological formation process is what gives each ruby its unique character, with color variations offering clues to its geographic provenance. This trace element composition is a key factor in the gem’s value and identity, distinguishing it from other corundum varieties, such as sapphire.
Gemological Properties
The ruby is renowned not only for its color but also for its remarkable durability, making it an ideal gemstone for jewelry intended for daily wear.
Color: The finest color of the ruby is described as a deep red with a hint of purple, a prized shade known in the trade as “pigeon’s blood.” This specific hue represents the pinnacle of ruby coloration and is highly sought after by collectors and jewelers.
Hardness and Durability: Ruby ranks an impressive 9 out of 10 on the Mohs Hardness Scale, making it second only to diamond in hardness among natural gems. This exceptional toughness means ruby jewelry can handle daily wear without showing signs of damage. Rubies are highly resistant to scratching and common wear and tear, a property that makes them perfect for rings, necklaces, earrings, and bracelets intended for regular use.
Chemical Composition: As a red variety of corundum, ruby’s chemical formula is Al₂O₃, with chromium as the trace element responsible for its color.

Care and Cleaning
Given its exceptional hardness, the ruby is a durable gemstone that is relatively easy to care for. Its resistance to scratching and abrasion makes it suitable for everyday jewelry. However, like all fine gems, it requires proper maintenance to preserve its brilliance.
- Cleaning: Ruby jewelry can be safely cleaned using warm water, mild soap, and a soft brush. Ultrasonic cleaners are generally safe for untreated rubies, but caution is advised for stones that have been fracture-filled or treated with heat. Steam cleaning should be avoided if the stone has undergone any fracture filling.
- Storage: To prevent scratching, store ruby jewelry separately from other gems and jewelry items, ideally in a soft cloth or lined jewelry box.
- Avoiding Damage: While ruby is highly durable, it is not indestructible. Avoid exposing ruby jewelry to sharp blows or extreme temperature changes, which could potentially damage the stone or its setting.
The ruby’s toughness ensures that with proper care, it can remain a stunning heirloom piece for generations, retaining its fiery beauty and symbolic strength.
