There are many materials on the market that pretend to be jaundice, such as kava stone, horseshoe gold, jade dyeing, serpentine rock staining, and dead seed dyeing. So how do we distinguish between Wada Huangyu and Huanglongyu? There are several ways to do this: The composition of Hetian Huangyu and Huanglongyu is different. Hetianhuangyu is mainly composed of tremolite and has a felt-like interweaving structure. The composition of Huanglongyu is mainly silica muscovite, etc. The main structure is a block structure and a strip structure. Annular band structure; Huanglong jade, relatively transparent. Lighting is easier to distinguish. Hetian jade topaz has a high hardness of 6.5, fine texture, strong toughness, typical grease luster, low transparency, and the hardness of Huanglong jade is usually higher than that of Hetian jade. The hardness of Huanglong jade is 6.5-7, transparency. It is higher than Hetian Huangyu. Both of them are observed from the naked eye. It feels that Huanglongyu is not as thick as Hetian Huangyu. The relative density of Huanglongyu is 2.595-2.61, and the relative density of Hetianhuangyu is 2.90-3.10. Under the same volume, Hetian Huangyu is heavier than Huanglongyu. The part of Huang Longyu's hype is relatively large, it is quartz stone, and Hetian jade is a kind of nephrite. The material of Huanglongyu is quartz, chalcedony or quartzite. Only quartzite with good texture can be called quartzite jade. Because of the wide distribution of nature, the price is not high, and the collection should be cautious. There are many types of "jade", some of which are not of high value, and Tibetans need to be vigilant.
