Most of the precious gems that are found on Earth are created by the combining of various chemicals at high temperatures and pressures deep in the Earth's crust. Others are created in laboratories that simulate those conditions.

Precious gems are typically classified based on their rarity, durability, beauty, and desirability. Some common examples of precious gems include diamonds, rubies, emeralds, and sapphires. These gems form through natural geological processes that involve high pressure and temperature conditions within the Earth's crust.

Many many many years ago, people would shave their gooch hairs. These shavings underwent a precipitational process in which they would form a chemical bond with each other. Over thousands of years they would become closer and more dense with each other, and eventually they geologically became coloured rocks, which are today known as gems. Strangely, this process does not work with pubic hairs - they create gold.
