How BIRTHSTONES and precious stones and natural -.

Deep in the earth molten rock and gas continues to go to the world's crust. Very high heat and pressure Peridot and diamond size. Diamonds start magma crystallization 109-149 miles below the Earth's surface and study Peridot 20-55 miles below. Because the world is constantly moving shell, this deposit can be found in the skin.

Gems are generally four cases although some jewelry, the training process more.

1. Otn liquids and liquefied gases.
2. The changes in the environment.
3. Surface.
4. The training covered the earth.

Jewelry created by magma.

Magma crystallization.

The mineral is used as liquid rock or magma, cools the way the world's crust. Several elements of the magma and mineral ores in May to make this part of the world's crust that rubies, sapphires, moonstone, garnet, zircon and fine - grained rocks.

Gas crystallization.

Some gems in the form of gas bubbles that occur when the magma pressure quickly such as volcanic eruptions. High concentration of different elements to create bubbles of grenades, Spinels and topaz.

Hydrothermal activity.

Sometimes, the water circulates through cracks in the surface of the floor and is used with certain elements such as fluorine, carbon dioxide, beryllium and other elements that are easily vaporized. Hydrothermal fluid mineral late May that the water or cracks in the surface veins. of minerals. Over time, temperature and pressure fields as crystal amethyst, topaz, emeralds and training.

Pegmatite.

The cavernous pegmatite volatile, evaporates quickly, or elements. Pegmatite elements crystallize in topaz, tourmaline, Kunzite, Morganite and aquamarine.

Gemma environmental changes.

When the host magma rocks, shells of the earth and volcanoes, the heat can melt the ice again and create new crystal more resistant to heat than ever. Lapis lazuli, garnets, spinels and diopside result.

When continental plates in the land of heat and pressure changes to the mountain. Mineral crystals that have become uncertain and is located in the new crystal, Tanzanite and create the type of grenades.

Surface.

The rain and water from lakes, rivers and seas can make a catch on rocks and other chemicals. Water level changes, because some of these stones on the floor or on the level of the reservoir. Turquoise, opals, rocks ?? necklace, amethyst, azurite, agate, and often late.

In the mantle.

Mantle is 83% of land and 1,864 miles of cold. A mantle and shell movement is continuous, pressure and temperature extremes. And "the terms of the combination is difficult humanitarian, diamonds.
