对这类水晶晶簇观赏石的欣赏与评价，主要是强调晶体的完整、品种的名贵（如紫水晶、烟晶、发晶等）、造型奇特、含有名贵晶体（如辰砂、辉锑矿等）伴生等。晶簇产于矿床晶洞中，长相完美的并不多见，要完整无损地采集下来，又比较困难，故而采集起来代价较大，精品晶簇价值也就昂贵了。

Bismuth (Bi) appears for being a metallic, but the number of electrons available for electrical conduction is similar to that of semiconductors. In actual fact, bismuth is called a semimetal. Molecular solids are usually crystals shaped from molecules or polymers. They may be insulating, semiconducting, or metallic, with regards to the sort of molecules from the crystal. New molecules are continuously becoming synthesized, and lots of are created into crystals. The volume of distinct crystals is big.

景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。

养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。

There are many various crystals based on geometric buildings, crystal development, and materials. There is often preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid constructions.

Encyclopaedia Britannica's editors oversee subject spots by which they've got considerable information, irrespective of whether from many years of experience gained by engaged on that written content or via review for a complicated diploma. They write new written content and confirm and edit material received from contributors.

A crystal method refers to the classification of crystals based upon the geometric arrangement and symmetry of their lattice constructions. There are actually seven primary crystal programs:

. The second layer is shaded while in the determine. It's the exact same aircraft-triangular composition; the atoms sit inside the holes formed by the very first layer. The first layer has two equivalent sets of holes, although the atoms of the second layer can occupy only one established. The 3rd layer, labeled C

水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。

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。

Binary crystals are found in lots of structures. Some pairs of elements form more than one composition. At room temperature, cadmium sulfide might crystallize both while in the zinc blende or wurtzite composition. Alumina also has two possible buildings at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals more info show distinct structures at different temperatures. Amongst the most complex crystals are those of silicon dioxide (SiO2), that has seven different constructions at many temperatures and pressures; the most typical of those buildings is quartz.
