①压电效�?在机械力(压力或拉�?作用下,水晶单晶体的两端会产生电荷,其电量相等但符号相反。在工业上,无色、无缺陷、不具双晶的水晶常被用来作压电石英片。

人造水晶分为熔炼水晶与养殖晶:据水晶专家汪毅的阐述,随着水晶的价值提高,喜欢的人增多,水晶也引起了作伪者的兴趣,现阶段中国水晶市场常见的造假方法为:

We've written about more than three hundred stones within the mineral kingdom! Examine each stone's one of a kind origin, background, and energies beneath.

水晶的价值还与块体大小有关,同样的颜色和净度级别,块越大越难得。有时候质量级别虽然低一些,但块体够大,也可能价格高于高级别的小晶体

This Review chronicles above two decades of study into making a genetic code for crystal engineering. Rather than directing Organic procedures, this code works by using artificial types of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each individual facet of the resultant structures could be systematically controlled. In this conceptual framework, the structural and useful innovations are explained in order to define the current degree of sophistication also to predict long run directions of your System.

水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手,但好的水晶一般大家都想得到,值与不值,就要看经验了。由于天然水晶的开采和制作原因,没有瑕疵的水晶很难得到,纯净的饰品要达到与合成水晶媲美的品质,实在是很难得。另外,由于水晶的特性,在佩戴过程中,也会改变其等级,比如因为某种原因,有可能会逐渐产生较大裂纹。
