They can be employed for many different things, not just for decoration. Lots of the first radios ever invented utilised crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Unique properties and harmonic capabilities of crystals for making highly exact measurements and adjustments.

③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline structure is characterised by a geometric, repeating pattern of symmetric molecular framework. The arrangement of atoms kinds these purchased, repeating designs.
Encyclopaedia Britannica's editors oversee subject parts in which they have comprehensive awareness, no matter whether from several years of experience attained by working on more info that articles or by way of examine for an advanced diploma.

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：
Crystals are absolutely nothing greater than an purchased arrangement of molecules or atoms. Crystals are available many different shapes and sizes, and each one has different properties. The things they are made of determines how it'll form.
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
16I opened the box and noticed a bit of crystal snowflake plus a greeting card with "Pleased Birthday" in the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。

水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
