Ruby gemstones are precious and valuable gemstones. Ruby made a loyal position in ancient times. It is a valuable gemstone due to its attractive color and hardness of 9.00 on the Mohs scale.
Rubies come from aluminum oxide or Corundum. Ruby gemstones come in different shades of red, which is determined by various elements. Chromic oxide gives the red color to ruby.
A pink or light color ruby stone exists due to the presence of chromium and iron. The rubies with the most intense shade of red have high levels of titanium.
In this exploration, we will embark on a fascinating journey, delving into the origins of various types of ruby gemstones. Each step unfolds a narrative of geological processes, cultural significance, and the mystical allure that surrounds these precious stones.
The Geological Genesis
To understand the diverse types of ruby gemstones, one must first explore their geological origins. Rubies are a variety of corundum, a mineral composed of aluminum and oxygen—the intense red color results from the presence of chromium in the crystal lattice during formation. The journey begins beneath the Earth’s surface, where geological forces conspire to create the perfect conditions for ruby formation.

Metamorphic Marvels:
The majority of rubies emerge from metamorphic environments, where high pressure and temperature cause changes in existing minerals. The marble and schist formations become the crucible for ruby formation, with Myanmar standing out as a significant source of metamorphic rubies. The Mogok Valley, often referred to as the “Valley of Rubies,” has yielded some of the world’s most exquisite stones.

Magmatic Mysteries:
Another intriguing origin lies in magmatic processes, where molten rock or magma contains the necessary elements for ruby formation. The heat and pressure during the cooling process create ideal conditions for corundum crystallization. The Montepuez region in Mozambique is renowned for its rubies born from such magmatic forces, presenting a distinctive character compared to their metamorphic counterparts.
