其它描述：《庶物异名疏》中说： �?水精出大秦国，一名黎�?�?。结晶完整的水晶晶体，就如参差交错的马齿，所以人们又叫它马牙石。先民们最早用它研磨成眼镜片，因而送它一个眼镜石的绰号。水晶有通称，也有俗称。广州一带称水晶叫晶玉，又名鱼脑冻；江苏东海县山民发现水晶会 �?窜火�?�?，于是给它起个放光石的俗名。世间一物多名，不足为奇，而像水晶拥有这么多的别称，实不多见。瞧，从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等，简直构成一部奇石鉴赏史。

Most reliable elements present in nature exist in polycrystalline form in lieu of as one crystal. They are actually composed of a lot of grains (compact crystals) packed with each other to fill all House. Every person grain has another orientation than its neighbours. Even though prolonged-range get exists inside of one grain, for the boundary concerning grains, the ordering improvements direction. An average bit of iron or copper (Cu) is polycrystalline.
