天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。
These advancements contain exotic structures with programmable lattice symmetries and well-defined crystal patterns, responsive components that leverage the intrinsic Homes of nucleic acids to control buildings on demand from customers, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals offering insights into light-weight–matter interactions. Looking ahead, we obstacle the Group to leverage the amazing structural Command afforded by crystal engineering with DNA to synthesize classes of functional materials that push beyond what is possible with naturally transpiring crystalline products or These produced by far more conventional approaches.
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。
. These four constructions comprise the vast majority of binary crystals with equal quantities of cations and anions.
Lattices may have a single lattice issue for every mobile or more than one, yielding a complete of fourteen Bravais crystal lattice types. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the a few-dimensional array made by a list of discrete details.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果

幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。
Crystals are not simply renowned for his or her Bodily look, but distinctive crystals of different supplies and formations may lead to an unlimited assortment of takes advantage of Crystal and Actual physical properties.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
