These crystals ended up formed around a million many years in the past inside the Earth's crust. They come about in the event the liquid while in the Earth consolidates plus the temperature chills. Other crystals form if the liquid makes its way through the clefts and dispense minerals in the clefts.
the solid point out of numerous uncomplicated substances, that have an everyday condition and surfaces arranged in comparable styles
10This may be the silicon chip—somewhat chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
《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。”
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
Hexagonal �?Characterised by four axes, 3 of which can be equivalent in length and intersect at 120 degrees, with a fourth axis perpendicular to the other 3.

22Working from what America currently here knows about itself, the bureau's experts and also other demographers offer you an irresistible, if clouded, crystal ball amongst their visions.
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 will find other minerals and molecules that will variety these crystal lattices. Snowflakes undoubtedly are a traditional illustration of a roughly symmetric and geometrically patterned construction from ice crystals, and gemstones of all types are generally crystals.
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
This crystal composition is chargeable for the distinctive physical and chemical Homes of sodium chloride, together with its large melting issue, electrical conductivity, and ability to kind ionic bonds easily.
