看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
A further exciting, and delicious, experiment is to sort huge crystals making use of sugar. By heating sugar with drinking water after which allowing this Alternative evaporate on sticks, you can type rock candy from sugar crystals!
对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。
Most sound elements found in character exist in polycrystalline sort rather than as an individual crystal. They are actually composed of millions of grains (tiny crystals) packed collectively to fill all space. Just about every specific grain has a different orientation than its neighbours. While prolonged-range buy exists within just one grain, at the boundary among grains, the ordering alterations route. A standard bit of iron or copper (Cu) is polycrystalline.
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
Lattices may have just one lattice point for each cell or more than one, yielding a complete of fourteen Bravais crystal lattice styles. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the 3-dimensional array made by a set of discrete details.
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。

多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
You'll find other minerals and molecules which will type these crystal lattices. Snowflakes absolutely are a typical example of a about symmetric and geometrically patterned structure from ice crystals, and gemstones of all types are generally crystals.
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。
Tetragonal �?Characterized by a few mutually perpendicular axes, two of which can be equivalent in length, while the third is extended or shorter and perpendicular to the other two.
