Geology and Gem Mining: From Underworld Origin to Sustainable Beauty

* * Gemstone mining is an industry that combines geological and mineralogical knowledge with advanced engineering to bring up minerals of beauty, durability and rarity from the earth's crust * *

Each mineral has specific temperature and pressure generative conditions. Understanding these geological environments is therefore the key to finding and determining the most appropriate mining methods.

# # # 1.Type of gem and geologic origin

The formation of gem ore is directly linked to rock cycles, both igneous, sedimentary and metamorphic rocks.

* * * Diamond (Diamond) * *: A diamond is a pure carbon crystal that forms in the Earth's flesh layer (Mantle) under immensely high pressure and temperature...

* * * Ruby (Ruby) * *: Ruby is a mineral in the corundum group....

* * * Sapphire * *: Sapphire is classified as a corundum mineral group...

* * * Emerald * *: Emerald is a mineral in the beryl group...

* * * Ulgemi (Tektite) * * *: Ulgemi was the origin of a meteor event hitting the earth...

# # # 2.Mining techniques and methods

The mining method is divided into 3 main methods, namely

* * * Alluvial Mining / Placer Mining (Alluvial Mining) * *: Apply to secondary mineral deposits...

* * * Open-Pit Mining (Open-Pit Mining) * * *: Used when the mineral line is near the surface...

* * * Underground mining (Subsurface / Underground Mining) * *: Used when deep mineral deposits...

# # # 3.Post-Mining & Gemological Processes

When the ore is extracted....

# # # 4. Environmental impact and the move towards sustainability

The mining industry creates economic value...
