Chaîne en gros en argent sterling le langage des gemmes

Cleavage is a plane that can be cleaved along a specific direction in a mineral crystal called a cleavage plane. This cleavage plane is related to the atomic structure of the mineral crystal. It is usually the part where the gemstone atoms are weakly bonded. Calledcleavage”. Many solid gems must be split along the cleavage plane. The famous Kleinan diamond is separated along the cleavage plane. The toughness of the diamond is lower than that of the jade because there is a set of obvious cleavage that allows it to be split. Because of cleavage, cleavage has a certain degree of influence on the toughness of gems.

Fracturerefers to the fracture surface where the gemstone is broken by a strong knock. The fracture surface is not split along the cleavage surface, because the fracture surface presented at the fracture site presents different shapes to help identify the gemstone. The appearance of the fracture can be divided into Conchoidal, Splintery, Grainy, Uneven and so on.

Pleochroism

The so-called pleochroism means that birefringent gemstones can be viewed from different directions to see different colors or different shades of color. This is caused by the refraction of the gemstone absorbing light of different wavelengths, so the crystal of the gemstone is observed from different directions Often present in different colors. Two colors are called Dichroisrn, and three colors are called Trichroism. The most obvious examples are tourmaline and tanzanite. Most other birefringent gemstones also have pleochroism, but they are not so obvious, so It is not easy to observe.

Amorphous

A gem with a fixed crystalline form is called an Amorphous gem, and Opal is the most typical amorphous gem.

Aggregate

Rock-like gemstones formed by agglomeration of multiple minerals, most of the gemstones formed in the natural world are actually mixed with other mineral components. There are not many crystals of pure single minerals. Émeraude, Lapis lazuli, etc.. are all polymer gems.
