Historical Background

Early Discoveries and Uses

Rubies were first discovered over 2000 years ago in the Mogok region of Myanmar, known for producing the finest rubies. They quickly became treasured possessions among royalty and the elite, symbolizing power and wealth.

Symbolism and Cultural Significance

Rubies have held various symbolic meanings across cultures. In ancient India, they were called "Ratnaraj," meaning "king of precious stones," and were believed to protect warriors in battle. In the medieval era, European royalty sought rubies for their purported protective qualities and their association with love and passion.

Ruby in Ancient Civilizations

In ancient Burma, now Myanmar, warriors wore rubies into battle to make them invincible. In China, rubies were buried under foundations to secure good fortune. Rubies were also traded along the Silk Road, spreading their allure across continents.

Geological Formation

Natural Formation Processes

Rubies form under extreme heat and pressure conditions, typically within metamorphic rocks like marble. Their red color comes from the presence of chromium within the corundum crystal structure.

Primary Mining Locations

The most famous sources of rubies include Myanmar, Thailand, and Sri Lanka. African countries like Mozambique and Madagascar have also become significant suppliers of rubies in recent years.

Synthetic Ruby Production

Synthetic rubies are created using methods like flame fusion and the Czochralski process. These rubies are chemically identical to natural ones but can be produced more cost-effectively and in larger sizes.

Physical and Chemical Properties

Chemical Composition

Rubies are composed of aluminum oxide (Al2O3) with trace amounts of chromium (Cr) giving them their characteristic red color. They rank 9 on the Mohs scale of hardness, making them exceptionally durable.

Physical Characteristics

Rubies exhibit a range of red hues, from pinkish-red to deep, blood-red, with the most valued being the "pigeon blood" red. They often contain inclusions, which can enhance their unique beauty.

Optical Properties

Rubies display strong pleochroism, meaning they show different colors when viewed from different angles. They also exhibit fluorescence under ultraviolet light, often glowing a vivid red.

Types and Classifications

Natural vs. Synthetic Rubies

Natural rubies are mined from the earth, while synthetic rubies are lab-created. Though they share the same physical and chemical properties, natural rubies are more valued due to their rarity.

By Source: Burmese, Thai, African, etc.

Burmese rubies are renowned for their intense red color and high quality. Thai rubies often have a darker, more garnet-like color, while African rubies, particularly from Mozambique, are appreciated for their vibrant hues and clarity.
