看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
A crystal composition focuses on how the atoms are organized Within the crystal. Even so, crystallographers have an interest in the overall form and dimensions of the crystal together with its external traits. To perform this, they should learn about the crystal system.
In order to see how crystals are shaped, you are able to do some task in your very own kitchen and find out the formation of your crystals occur with your have eyes . This can be performed by putting a small quantity of desk salt into some standard tap h2o, wait 24 hours, and you will see good cubed formations. This takes place because the water is evaporating, which leads to the atoms which make up the salt (the mineral) as well as the water to return nearer together.
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。

Crystals are almost nothing much more than an purchased arrangement of molecules or atoms. Crystals are available in a variety of sizes and styles, and each one get more info has distinctive qualities. What they are made of determines how it'll form.
Lots of crystals behave like butter in that they are tricky at lower temperatures but soft at increased temperatures. They are really termed solids at all temperatures underneath their melting stage. A doable definition of a sound can be an object that retains its condition if still left undisturbed. The pertinent concern is just how long the article retains its shape. A hugely viscous fluid retains its form for one hour but not a year. A stable have to preserve its shape more time than that.
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。
There are 2 this kind of achievable periodic preparations. In Just about every, the very first layer has the atoms packed into a airplane-triangular lattice in which each and every atom has 6 rapid neighbours. Figure 2 demonstrates this arrangement with the atoms labeled A
The sodium chloride crystal lattice is characterized via the near packing with the beneficial sodium ions and negative chloride ions. Each and every sodium ion is surrounded by 6 chloride ions, and every chloride ion is surrounded by six sodium ions, creating a extremely secure and symmetrical composition.
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。
This crystal construction is answerable for the special Actual physical and chemical Attributes of sodium chloride, together with its higher melting issue, electrical conductivity, and ability to form ionic bonds conveniently.
