水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。
水晶原石观赏石充分体现了天然水晶的本质，经过抛光的水晶原石观赏石，玲珑剔透、晶莹璀璨，独具匠心的设计，恰到好处地显露出水晶的魅力。如果您想单纯的欣赏水晶，水晶原石观赏石是你的不二之选，给人一种返璞归真的感觉。
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。
Tetragonal: These crystals type prisms and double pyramids. The composition is sort of a cubic crystal, besides 1 axis is lengthier than one other.
How Crystals Form The whole process of forming a crystal is named crystallization. Crystallization frequently occurs whenever a solid crystal grows from a liquid or Remedy.
Lattices may have one lattice level per cell or more than one, yielding a complete of 14 Bravais crystal lattice varieties. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the three-dimensional array created by a set of discrete factors.
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：

水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
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。
One crystals of metals are delicate and malleable, while polycrystalline metals are more difficult and stronger and are more practical industrially. Most polycrystalline components is usually built into substantial solitary crystals right after extended heat procedure. In past times blacksmiths would warmth a bit of steel to really make it malleable: heat will make a handful of grains improve big by incorporating smaller sized kinds. The smiths would bend the softened metal into form after which you can pound it awhile; the pounding would enable it to be polycrystalline all over again, expanding its toughness.

《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
Binary crystals are present in lots of structures. Some pairs of components sort more than one composition. At area temperature, cadmium sulfide may possibly crystallize either in the zinc blende or wurtzite construction. Alumina also has two achievable buildings at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit diverse constructions at here distinct temperatures. One of the most sophisticated crystals are All those of silicon dioxide (SiO2), which has 7 distinctive buildings at a variety of temperatures and pressures; the most typical of these buildings is quartz.
