Man-made Crystal

It is also called "raising crystal”. The stone is without six crystallizations, and this is the easiest way to judge. But after grinding, the above method is bad, and we have to distinguish by ultraviolet spectrometer. On the market the mostly seen is colorless transparent white crystal, amethyst, citrine and water blue crystal counterfeiters. Here I suggest you, friends, if you happen to meet a controversial crystal mineral, you’d better send it to the justice of the third party, such as identification, to identify and distinguish. It doesn’t cost much, but have professional security. If necessary, you can even send two or more for identification. It’s the best to choose the original stone. We can see from crystallization, grow grain and the compatible material, and that will never be wrong. In addition, to buy crystal mineral with inclusion, ordinary people mistakenly call for impurities or defect, is correct. Actually, it is "growth in nature" best proof.

Jade hand-processing operations

Jade needs the operations of the sculpture and hand-processing. Hand-carved jade is a clear distinction between other jewelry processing jobs. After years of growth, stone artist's each division for a jade's carving should consider many times. They must take into account the kinds of raw materials, water, and color, leather, fog, and meat, cotton, and other aspects of the comprehensive causes of lock, thus to be symptomatic under materials. This is entirely different from the available large-scale mechanized production of jewelry manufacturing.

In addition, compared to other collections, jade's collection have their own security. Irrespective of where it was or worn on the body, it do not like the paintings or antique wood's concerns of damp or moth. The whole auction market is jade's barometer of the high-end collector market.
