History and Lore
Ruby has been a source of fascination for civilizations across the globe.

In ancient times, ruby was considered one of the most precious gemstones, often referred to as the "King of Gems." Its value was not only monetary but also spiritual and symbolic.
In many ancient cultures, ruby was believed to possess protective qualities. In India, for example, ruby was considered sacred and was thought to bring prosperity and divine favor. Ancient Chinese emperors believed that rubies contained the life force of the universe and wore them to maintain their health and vitality. These beliefs underscore the deep cultural significance of ruby in the East.
In medieval Europe, ruby was also highly prized. It was often incorporated into royal regalia and was seen as a symbol of power and authority.

These associations with strength and protection have contributed to ruby's enduring popularity across different eras and regions.

Geological Formation and Sources
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). What distinguishes ruby from other corundum varieties, such as sapphire, is the trace element chromium, which gives the gemstone its characteristic red color. The presence of chromium causes the absorption and reflection of specific wavelengths of light, resulting in the deep red hue that makes ruby so distinctive.
The formation of ruby requires specific geological conditions. It typically forms in metamorphic rocks, where intense heat and pressure cause the transformation of minerals over millions of years. These conditions are most commonly found in regions with a history of tectonic activity, such as parts of Southeast Asia, Africa, and South America.
Historically, the most famous sources of ruby have been in Myanmar (formerly Burma). Burmese rubies, particularly those from the Mogok region, are renowned for their rich red color and high quality. Other notable sources include Thailand, Sri Lanka, and more recently, Madagascar and Tanzania. Each of these locations produces rubies with slightly different characteristics, but all share the gemstone’s fundamental properties of hardness and brilliance.
The hardness of ruby is one of its defining features. It ranks at 9 on the Mohs Hardness Scale, making it second only to diamond in terms of durability. This high hardness makes ruby suitable for everyday jewelry wear, as it is resistant to scratches and other forms of damage.
Gemological Properties
Ruby is a gemstone of exceptional quality, characterized by its deep red color and remarkable durability. The following are key gemological properties of ruby:
| Property | Description |
|---|---|
| Chemical Formula | Al₂O₃ (aluminum oxide) |
| Hardness (Mohs) | 9 |
| Refractive Index | 1.76–1.78 |
| Specific Gravity | 3.95–4.10 |
| Color | Deep red, ranging from purplish red to orangey red |
| Luster | Vitreous (glassy) |
| Transparency | Transparent to translucent |
| Cut | Commonly cut in brilliant, emerald, and rose cuts |
| Inclusions | Often contains inclusions such as silk, needles, and rutile crystals |
The deep red color of ruby is primarily due to the presence of chromium. The most desirable color is a vivid red with a slight purplish or orangish tint. This color is often referred to as "pigeon blood," a term commonly used to describe the finest Burmese rubies.
Ruby is also known for its excellent luster and brilliance. When properly cut, it can display a fire and sparkle that rival that of diamonds. The high refractive index of ruby contributes to its brilliance, allowing light to enter the gemstone and reflect off its internal surfaces.
Due to its hardness, ruby is suitable for a wide range of jewelry styles, from rings and pendants to bracelets and earrings. However, because ruby can have inclusions or cleavage planes, it is important to handle and clean ruby jewelry with care to avoid damage.

In China, it was believed to contain the essence of life and was worn by emperors to maintain their health and vitality.
