天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
the sound point out of numerous very simple substances, that have a daily form and surfaces arranged in related designs
A primary thought in crystal buildings is the unit cell. It is the smallest device of quantity that allows equivalent cells to be stacked collectively to fill all Area. By repeating the pattern from the unit mobile again and again in all directions, your entire crystal lattice might be constructed. A cube is The only example of a unit mobile. Two other illustrations are revealed in Figure one. The first would be the device mobile for just a deal with-centred cubic lattice, and the 2nd is to get a body-centred cubic lattice. These buildings are discussed in the following 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�?”

⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
Q.4. What is the difference between atomic composition and crystal construction? Ans. The principal difference between atomic framework and crystal composition lies within their definitions: atomic framework refers to how atoms are structured in a one molecule or even a cluster of molecules, Whilst crystal construction concerns the particular arrangement of atoms inside of a solid compound.
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。
The arrangement of an atom’s electrons establishes its chemical click here Qualities. The Homes of solids are often predictable within the Attributes in their constituent atoms and molecules, and different shell constructions of atoms are for that reason answerable for the range of solids.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
Tetragonal �?Characterised by 3 mutually perpendicular axes, two of which can be equivalent in length, even though the third is longer or shorter and perpendicular to another two.
