The ruby, a gemstone synonymous with passion, protection, and vitality, holds a prominent position in the world of precious stones. Revered for its vibrant red hue and exceptional durability, it is the birthstone for July and a symbol of enduring love and courage. This article delves into the history, geological origins, gemological properties, and cultural significance of the ruby, drawing upon available sources to provide a comprehensive overview of this captivating gemstone.
History and Lore
The ruby’s history is steeped in lore and legend, stretching back millennia. Its intense color has long been associated with blood, life, and power, leading to its veneration in numerous cultures. The ruby is one of the “Big Three” gemstones, alongside diamond and sapphire, recognized for their importance and value. Sources indicate that rubies and sapphires both belong to the corundum family, with color being the primary differentiator between the two.
The name “ruby” itself is derived from the Latin word ruber, meaning red. Ancient civilizations, including the Hindus, Burmese, and Greeks, attributed mystical properties to the stone. In some cultures, rubies were believed to protect warriors in battle, ensuring victory and preventing wounds. They were also associated with royalty and nobility, often adorning crowns, scepters, and other symbols of power.
Geological Formation and Sources
Rubies are formed in metamorphic and igneous rocks. Their red color is a result of the presence of chromium, though other elements can also contribute to the hue. The intensity of the red color, ranging from dark orange-red to purplish-red, is a key factor in determining a ruby’s value. A gemstone must have a dominant red color to be classified as a ruby; reddish-orange stones are considered orange sapphires, and reddish-purple stones are purple sapphires.
While rubies have been sourced from various locations around the world, specific regions are particularly renowned for their high-quality stones. Historically, the Ural Mountains of Russia were a significant source, with a notable discovery occurring in 1830 coinciding with the birthday of Czar Alexander II, leading to the stone being named in his honor and becoming the national stone of Russia. However, current sources are not detailed in the provided materials.

The value of a ruby is determined by several factors, including color, clarity, cut, and carat weight. Fine rubies are transparent with minimal inclusions that do not affect their clarity. The most coveted rubies exhibit a vibrant, pure red hue.

Symbolism and Metaphysical Beliefs
Throughout history, the ruby has been imbued with symbolic meaning. It is widely regarded as a symbol of passion, love, vitality, energy, courage, and protection. The stone’s association with blood has contributed to its connection with life force and power.
The provided sources also mention that rubies symbolize strength, invincibility, and purity. These symbolic associations have made rubies popular choices for engagement rings and other jewelry intended to represent enduring commitment and affection.
Market Value
The ruby consistently ranks among the most expensive birthstones. Sources indicate a price range of $3,000 to $12,000 per carat, placing it as the second most expensive birthstone after diamond. The value is heavily influenced by the quality of the stone, with larger, more intensely colored, and clearer rubies commanding the highest prices.
The scarcity of high-quality rubies also contributes to their value. The closure of the Argyle diamond mine in Western Australia, a significant source of pink diamonds, has further emphasized the rarity of colored gemstones, including rubies.
Care and Cleaning
Due to its exceptional hardness, the ruby is a relatively durable gemstone. However, it is still susceptible to damage from harsh impacts or abrasive materials. To maintain its brilliance, rubies should be cleaned regularly with warm, soapy water and a soft brush. Ultrasonic cleaners should be avoided, as they can potentially damage the stone. It is also advisable to remove ruby jewelry before engaging in strenuous activities or when exposed to harsh chemicals.

Its rich history, vibrant color, exceptional durability, and symbolic associations have cemented its place as one of the world’s most prized possessions.
