The History of Ruby Gemstones


Rubies, with their fiery red brilliance, have been cherished throughout history by various cultures and civilizations. The word “ruby” derives from the Latin word “rubeus,” meaning red. Ancient cultures believed rubies held mystical properties, including protection against misfortune and enhancing courage.


Rubies were revered by Indian royalty, where they were known as “ratnaraj” or “king of precious stones.” The famous “Burmese Ruby Tiara” and the “Timur Ruby,” a historical gemstone set in the British Crown Jewels, are iconic examples of ruby’s significance in royal collections.


Where Do Most Rubies Come From

The majority of high-quality rubies originate from a few key regions, notably:


Myanmar (Burma): Renowned for producing the finest rubies with a vivid red color known as “pigeon’s blood,” Burma has long been the primary source for top-quality rubies.


Thailand: Thailand is a major hub for ruby processing and trading. Many rubies from other regions are brought to Thailand for cutting, enhancing, and distribution.


Mozambique: In recent years, Mozambique has emerged as a significant source of rubies, producing gems with beautiful red hues that rival those from Myanmar.


How Are Rubies Made

Formation: Rubies are a variety of the mineral corundum, which is an aluminum oxide. They are formed in specific geological environments under high heat and pressure, typically in marble, basalt, or granulite rock formations. The presence of chromium is responsible for the deep red color of rubies.


Heat and Pressure: The formation of rubies requires a combination of intense heat and pressure. These conditions can be found in regions where tectonic forces push rocks deep within the Earth’s crust, subjecting them to the necessary conditions for corundum to crystallize.


Magma Intrusion: In some cases, magma intrusions can create the right conditions for rubies to form. When molten rock (magma) moves through existing rock formations, it can introduce elements like chromium, which is essential for the red coloration of rubies, into the mix.


Crystallization: As the mineral-rich fluids cool down within the rock formations, the corundum crystals, including rubies, begin to form. The process of crystallization is slow and can take millions of years to produce gem-quality rubies.


Erosion and Uplift: Over time, geological forces, such as erosion and tectonic uplift, bring these rubies closer to the Earth’s surface. They can be brought to the surface through volcanic activity or the gradual wearing away of overlying rocks.


Mining: Once rubies are discovered near the surface or in gem-rich deposits, they are mined. Mining methods can vary, from traditional hand tools to modern machinery, depending on the location and accessibility of the deposit.


Cutting and Polishing: After being extracted from the earth, rough rubies are carefully cut and polished by skilled lapidaries to bring out their beauty and brilliance. The cut is a crucial factor in maximizing a ruby’s color and luster.


How Hard Are Rubies Compared to Diamonds

Rubies are durable gemstones, registering 9 on the Mohs scale of hardness. This places them just below diamonds, which are the hardest natural substance with a Mohs hardness of 10. While rubies are not as hard as diamonds, their durability makes them suitable for everyday wear and an excellent choice for jewelry.
