What Exactly Is a Gemstone?
Have you ever wondered or asked yourself, what exactly are gemstones and what are they made of? Gemstones are made from inorganic minerals mined out of the ground. There are over 4500 different minerals, however, only about 100 are used to make gemstones. There are also gemstones such as pearl, ammolite, amber, and jet, which are made from organic material. Emerald is a silicate that contains aluminum and beryllium. The green color in an emerald crystal result from traces of the minerals vanadium and chromium. If the aluminum is replaced with manganese, red beryl is the result, another type of gemstone. Beryl can be pink, white, or yellow, depending on which trace elements are present in the molecular structure.
Corundum
Aluminum and iron create the mineral corundum. When titanium is added to this, the blue
sapphire gemstone is the result. Sapphires can be blue, green, purple, orange, yellow, or red. Red sapphires are actually the ruby gemstone. Rubies get their red color from chromium, while sapphires get their clue color from iron and titanium.

Structures
Differing crystalline structures also result in various colors within minerals. All minerals are crystallized, and most gemstones are minerals. The slightest change in formula or pressure can produce dramatically different results in different compounds.These various elements and substances have been chosen for their beauty, durability and rarity. From an initially rough rock-like state, the stones are cut, faceted, and polished to make jewelry or various other adornments. They can also can be used as personal conversation pieces in one’s home or exhibited in museums.

Renowned Mine in Brazil
In the mountains of southern Brazil, in Minas Gerais, many precious gemstones are mined from deep in the Earth. The miners used power drills to punch holes in the face of the shaft. After inserting dynamite into the holes, they then attach fuses and detonators. Then charges are set off creating explosions to break up the granite rock. Then the heavy work begins as the miners bring up the rock by hand to the surface. Most of the crystals in the rock will be too small to be seen with the naked eye, and even among the larger crystals, few will be considered gem quality. Conditions to form gemstones that are transparent and have beautiful color don’t occur very often.
