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。
Bismuth (Bi) seems to generally be a steel, but the quantity of electrons readily available for electrical conduction is similar to that of semiconductors. In truth, bismuth is named a semimetal. Molecular solids are generally crystals formed from molecules or polymers. They are often insulating, semiconducting, or metallic, according to the variety of molecules in the crystal. New molecules are consistently becoming synthesized, and many are made into crystals. The volume of different crystals is big.
发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。
诗中道出一段唐代由盛变衰的史实。玄宗末年，杨贵妃得宠，三姐妹并封为国夫人。他们养尊处优，奢华至极，仆人用水晶盘将珍馐佳肴端到宴席上，美人觉得没有口味，懒得动筷子。作为“诗圣”作为“史诗”，紫驼一段写饮食之精美，不空发议论，只尽情揭露事实，无一刺讥语，无一慨叹声，却使人于以外得之：此诗之善讽也。以史为鉴，这样的世道，这样的人物，国家不出“安史之乱”那样的大祸反倒不正常了。

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�?。

仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。

The fundamental models of solids are either atoms or atoms that have put together into molecules. The electrons of an atom go in orbits that variety a shell composition within the nucleus. The shells are crammed in a scientific order, with Each individual shell accommodating only a little quantity of electrons. Different atoms have unique quantities of electrons, that happen to be distributed in the attribute electronic framework of stuffed and partly loaded shells.

水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。
