Gemstones — formed over millions of years by earth’s geologic processes, like cooling magma, plate tectonics, and even erosion — bring a naturally captivating narrative to fine jewelry design.

As A Result, 'Veins' Of Minerals Fill Preexisting Cracks.
• gems are beautiful, rare, and durable. Aluminum oxide, as it is known in mineralogy circles, is formed by both volcanic processes deep in the earth and the high pressure and temperature, conditions of metamorphic processes.

There are many gemstone treatments and enhancements used to improve natural gemstone rough. Thousands or even millions of years ago, nature created the vast majority of natural gems we can now find through one of three processes. The majority of gemstones are formed by metamorphism.
However, The Evidence Shows That Some Gems Actually Form In The Mantle.
