Common defect of the gemstone jade cufflinks

In fact, the emerald cufflinks and nephrite are two completely different areas: emerald belongs gem, emerald cufflinks are jade cufflinks. So, What is the difference of gems and jade cufflinks? Any other gem cufflinks do no have this trait.
 Generally speaking, the gem is based on a natural single crystal mineral that is a gem, is usually taken from a separate crystal, crystal with our naked eye can see (so called the crystal), precious stones are usually transparent, light enter the internal cut gem, refracted through a series of reflection, we can see the flash of gems such as rubies, sapphires, emeralds, etc.; precious stones are also a few are natural mineral aggregates such as opal, lapis lazuli, but also There are some organic matter, such as amber, pearl, coral, ivory, including within the broad stones, they are also known as bio-precious stones. This method can only be mastered through training to realize the subtle differences of the cufflinks.  Jade cufflinks is another concept, which is composed of numerous tiny the naked eye can not see the crystal in the high-powered electron microscope.
 We can see its structure, so people called the jade cufflinks aphanitic minerals Broadly speaking, the collection of these tiny crystals are known as jade cufflinks. Usually referred to people talk about jade cufflinks mainly refers to nephrite (white for the typical color) and emerald cufflinks (typical color), two kinds of jade cufflinks is internationally recognized as a valuable jade cufflinks . The gems are usually transparent, extremely smooth surface, the surface of stones ability to reflect light, and light can enter the gem internal good after the reflection and refraction of high net to leave the gems reach our eyes, so we see cutting The gems are usually always shining. Jade cuff links because it is composed of numerous tiny crystals, crystal always have gaps, so no matter how good the master polishing processing. The diamond cufflinks also have the features of straight lines. 
 It is impossible to achieve the degree of polish of the gem surface, the light at the jade cufflinks surface formation trajectory as the sun shines on the waves on the lake, this effect is called diffuse reflection. If you have interest in contrast to the surface gloss, can take a closer look at their own windows and shower room frosted glass of the difference, whether it is more smooth and shiny, the stronger? So we usually see the jade surface is moist or oily texture. Diamond surface finish of the cufflinks is very smooth. The light is very little depth gem interior, so we usually feel jade cufflinks translucent, of course, an exception is also top of the emerald cufflinks can also be almost transparent. Common defect of the gemstone jade cufflinks.Intrusive body residues at the top of dolomitic marble xenoliths or tongue body and magma intrusion body and hydrothermal contact metasomatic formation of diopside, petrochemical, forsterite, and tremolite alteration, Chengyu material conditions one. Late Variscan intrusions derived shallow acidic dikes intruded into the alteration zone of dolomite marble, the recurrence of contact metasomatism in the appropriate geological conditions (300-350 degrees Celsius, 2.5 kbar below and certain torsional stress), and Hetian jade form. These four stages can be summarized as follows: A late Mesoproterozoic epicontinental sea sediment / sedimentary dolomite (the Chengyu material one of the sources). Therefore, you will feel sticky if you touch the surface of the diamond cufflinks with the fingers.
Proterozoic late Tarim movement, regional metamorphism / dolomite metamorphic dolomite marble (as jade material and structural transformation. Late Variscan acidic intrusive activities, contact metasomatism / formation of dolomite marble alteration zone (Chengyu material basis). D, Late Variscan intrusions derived acidic dykes contact metasomatism and / Hetian jade formation. Will always be some difference of emerald and jade cufflinks confused, because they are transparent and exudes a charming green sheen.
