In chromatology, the three elements of hue, lightness and saturation are used to describe colors.

Hue, also called hue, refers to the distinguishing characteristics of red, orange, yellow, verde, cyan, albastru, and purple. The hue depends on the selective absorption of visible light by the gem.

Brightness, also known as brightness or hue, is the perception of the brightness of a gemstone by the human eye, which depends on the degree of reflection and transparency of the gemstone.

Saturation, also called chroma, refers to the density or vividness of colors.

Causes of gem color:

In traditional gemology, the causes of gem color are divided into three categories: white, other colors, and false colors according to the chemical composition and external structure characteristics of gems.

Self-color refers to the color caused by the main elements in the chemical composition of gems, cum ar fi turcoazul, malachite, olivine, almandine, etc..

Other color refers to the color caused by the trace elements in the chemical composition of the gem. De exemplu, the chemical composition of corundum is Al2O3, when it is pure Al2O3, it is colorless; when it contains traces of chromium, it is red, which is ruby; the blue of sapphire is that corundum contains traces of iron and titanium. Caused by.

False color, false color has nothing to do with the chemical composition and crystal structure of gemstones, but is related to the physical effects of light, such as the color change of opal, the halo of labradorite.

În plus, gems also have pleochroism.

The optical properties of heterogeneous colored gemstones vary with the direction, and the selective absorption of light waves and the total intensity of absorption also vary with the direction. This phenomenon in which the color of the gemstone changes due to the different vibration directions of the light waves in the gemstone crystal is called pleochroism.

Colored transparent heterogeneous gemstones can have dichroism or trichromism, and are divided into strong, medium, and weak according to their relative strength.

For colored gemstones, pleochroism is an important optical property. The pleochroism of different kinds of gemstones is generally different, including the color and strength of pleochroism. The apparent degree of pleochroism is related to the nature of the gem, and is also closely related to the direction of the cut surface of the gem. Generally, pleochroism is most obvious in the plane parallel to the optical axis or the plane parallel to the optical axis, while the plane perpendicular to the optical axis does not show pleochroism.
