具体而言,可以通过鉴定玉石的密度和硬度来进行估价。比如,常见的大理石、石英岩、钠长石玉密度较低,市面上伪造的玉石也往往质量很次,密度更低,真玉石和真翡翠则不仅密度高,而且硬度也比较大,它们明显高于那些假的玉石。其次,玉石作为纤维交织结构、块状构造珍品,在放大镜的观察下,我们还能观察到它特殊的结构,它的韧性要远远高出粒状结构的大理石和石英岩,这一点也是很好的鉴定方法。
Specifically, it can be evaluated by identifying the density and hardness of the jade. For example, common marble, quartzite, sodium feldspar jade density is low, the market of forged jade is often very poor quality, density is lower, true jade and true jade is not only high density, and hardness is also relatively large, they are significantly higher than those fake jade. Secondly, jade as a fiber interwoven structure, block structure treasures, under the magnifying glass observation, we can also observe its special structure, its toughness is far higher than the granular structure of marble and quartzite, which is also a good identification method.
