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：
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
《全唐诗》卷七八五载《白雪歌》：“鸟啄冰潭玉镜开，风敲檐溜水晶折。”
结晶�?When sea h2o is allowed to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
There is a related directive about crystal glass which differentiates concerning full direct crystal, lead crystal and crystal.
Crystals are frequently viewed as a thing of enormous natural beauty, plus they are commonly made use of with diamonds or other stones to create items of jewellery. Virtually all crystals now are man-made in laboratories.
A crystal system refers back to the classification of crystals determined by the geometric arrangement and symmetry in their lattice structures. You'll find 7 main crystal techniques:
. The 2nd layer is shaded in the determine. It has a similar airplane-triangular structure; the atoms sit in the holes fashioned by the main layer. The 1st layer has two equal sets of holes, more info however the atoms of the 2nd layer can occupy only one established. The 3rd layer, labeled C
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（advancement lines）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
crystal, any sound material where the part atoms are organized inside of a definite sample and whose surface regularity reflects its internal symmetry.
