Geological Origin of Rubies

The story of a Ruby starts deep within the earth, under high-pressure and temperature conditions. Don’t underestimate the fascinating journey that this mesmerizing gemstone undertakes, a journey that requires precise conditions to yield this sought-after jewel.

The formation process of rubies

A ruby’s narrative begins nearly 150 kilometers beneath the earth’s surface, where heat and pressure form a precise environment to create these extraordinary stones. Aluminium oxide, the principal component of rubies, is subjected to temperatures of around 2000 degrees Celsius and colossal pressures. This environment leads to the crystallization of rubies. The most captivating part? Rubies slowly ascend to the surface through a diverse range of geological activities, such as erosion and tectonic activity, making them available for mining and crafting into beautiful jewelry pieces.

Minerals and elements essential in ruby creation

Rubies owe their magnificent red hue to the presence of the element Chromium. Tiny traces of Chromium produce the vibrant red color that distinguishes rubies from other gemstones. Occasionally, traces of Titanium and Iron may also infiltrate the crystallization process, resulting in different hues and varieties of rubies. Minerals such as corundum play a crucial role in the formation of rubies, as pure corundum is almost colorless while traces of certain impurities create different gemstones, including rubies.

The geological conditions leading to ruby genesis

High pressure and temperature alone do not result in the creation of rubies; specific geological conditions are also crucial. The incidences where these conditions transpire occur in scarce locations throughout the world, explaining the rarity of rubies. You can find ruby deposits predominantly in metamorphic rocks such as marbles or certain types of basalt. It’s indeed a rare geological ballet, providing an extraordinary performance that ends with the birth of a ruby.
