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。
the good state of many easy substances, which have a regular form and surfaces organized in related patterns
A basic concept in crystal structures would be the unit mobile. It's the smallest device of quantity that permits identical cells to be stacked with each other to fill all Room. By repeating the pattern from the device cell time and again in all Instructions, the entire crystal lattice may be made. A dice is The only illustration of a unit mobile. Two other illustrations are proven in Figure one. The initial may be the device mobile for a encounter-centred cubic lattice, and the second is for your overall body-centred cubic lattice. These structures are spelled out in the next paragraphs.
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
Fig. 4: Creating blocks with diverse shapes and surface area chemistries direct the development of unique crystal symmetries.
Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, though the third is perpendicular towards the plane of the other two.
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
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：
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
16I opened the box and saw a piece of crystal snowflake in addition to a greeting card with "Happy Birthday" inside 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。
Crystallography will be the examine of crystals, and it bargains with every thing from best geometric styles to seemingly random conglomerations of particles and minerals.

A further type of crystalline carbon is predicated on a molecule with sixty carbon atoms called buckminsterfullerene (C60). The molecular shape is spherical. Each and every carbon is bonded to a few neighbours, as in graphite, as well as spherical shape is attained by a mix of twelve rings with 5 sides and twenty rings with 6 sides. Comparable constructions ended up first visualized from the American Crystal architect R. Buckminster Fuller for geodesic domes.
