silver jewelry wholesale china Baolong shares: the transparency and luster of gems

Zveřejněno na podle Kingjy

The optical characteristics of gems refer to the special properties of gems when they absorb, reflect and refract visible light, as well as the interference and scattering of visible light in gems.

Transparency is the ability of a gemstone to transmit visible light. It is usually divided into transparent, semi-transparent and opaque levels.

Transparency: The gem allows most of the light to pass through, and the bottom image is clear and distinct after being observed through the gem. Such as colorless crystal.

Translucent: The gemstone allows part of the light to pass through. Observe the objects behind it through the gemstone. The bottom image is blurred and only the outline shadow is seen. Such as black chalcedony.

Opaque: The stone basically does not allow light to pass through, the light is absorbed or reflected, and the objects behind it cannot be observed through the gem. Such as black chalcedony.

Luster is the ability of a gem surface to reflect light, and it reflects the brightness of the gem surface. Luster depends to a large extent on the refractive index of the gemstone and also depends on the degree of polish of the gemstone.

In gemology, luster can be divided into metallic luster, semi-metallic luster, diamond light beacon, and glass luster from strong to weak.

Metallic luster is the luster of natural gold, stříbro, and platinum; diamond luster is the strongest luster among non-metallic minerals, and it is also the best luster that transparent gems can display, such as the luster of diamonds. Glass luster is the light ocean that most transparent gems do not show, such as ruby, emerald, spinel and so on.

Due to the difference in the degree of polishing and structural characteristics of gems, the characteristics of reflection will vary, forming some special luster:

1. Grease gloss-very fine rough surface shows gloss like grease surface. Such as nephrite.

2. Waxy luster-the luster due to uneven surface, weaker than grease luster. Such as chalcedony and turquoise.

3. Resin gloss-refers to the gloss of some soft gemstones, such as the resin surface. Such as amber.

4. Silk luster-the luster of silk due to fiber structure. Such as malachite, tiger eye stone.

5. Pearl luster-soft and colorful reflection and interference phenomenon formed by many tiny parallel surfaces. Such as pearls.

Luster can make gems brighter, and at the same time, different luster also provides useful clues for identifying gems. But there is no clear boundary between various glosses.
