Gemstones are naturally occurring minerals that are prized for their beauty, durability, and rarity. They are formed through a variety of geological processes, and can be found in all parts of the world.
How gemstones are formed
There are three main ways that gemstones are formed: igneous, metamorphic, and sedimentary.
Igneous gemstones: Igneous gemstones are formed from molten magma that cools and solidifies. As the magma cools, minerals crystallize out, and some of these minerals may form gemstones. Examples of igneous gemstones include diamonds, sapphires, and rubies.
Metamorphic gemstones: Metamorphic gemstones are formed when existing rocks are subjected to high heat and pressure. The heat and pressure causes the minerals in the rocks to recrystallize, and some of these minerals may form gemstones. Examples of metamorphic gemstones include jade, garnet, and turquoise.
Sedimentary gemstones: Sedimentary gemstones are formed when layers of sediment are compressed over time. The pressure causes the sediment to harden into rock, and some of the minerals in the rock may form gemstones. Examples of sedimentary gemstones include amber, opal, and pearls.
Where gemstones are found
Gemstones can be found in all parts of the world, but they are most commonly found in areas with active geological processes, such as mountain ranges and volcanic regions. Some of the world’s most famous gemstone deposits are located in Australia, Brazil, China, India, and Sri Lanka.
