Emerald make finished processing divide all body and carving two big class into, mere body finished product have relatively high expectations for raw materials, there can't be crackle. Still should pay attention to cutting the worker's proportion while appraising, the thickness of the products is and symmetrical, for example cutting worker's good ' the egg ' can't cross thick or should be in the centre when being located in to cross the thin ' divine ', and the proportion should be moderate. There is jadeite isolated, generally conceal with the carving. Appraise flower weigh its aesthetic feeling degree and carve worker meticulous mainly when the piece. If the emerald plants the quality ordinarily, but will carve to workers exquisitely, value increases.

The tiny crackle will undoubtedly influence the value of the emerald slightly, but does not not affect the whole. However, it is a serious shortcoming to run through crackle of one of jade of monoblock. Generally speaking, shine the existence of the crackle of very easy perception with the torch.

These artificial to deal with until naked eye easy to perceive, but infrared to absorb spectrocomparator can supervise and does not contain the epoxy resin, the malachite dealt with, structure or destroying. Another method to dye, make emerald seem jade green, this what is called " C" Goods, it has already been surmounted ' dealt with ', has pretended to be, so is comparatively easy to penetrate.

Summarize as follows now:

A The goods: Original stone primary color, the man can be in order to pass on from generation to generation without the jade articles of the chemical disposal, its price is also relatively high.
