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。

Another pleasurable, and tasty, experiment is usually to sort significant crystals utilizing sugar. By heating sugar with water and after that allowing this Alternative evaporate on sticks, you could sort rock candy from sugar crystals!

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。

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。

⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。

②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。

Several crystals behave like butter in that they are challenging at small temperatures but comfortable at bigger temperatures. These are identified as solids in any way temperatures underneath their melting level. A probable definition of a strong is undoubtedly an object that retains its shape if still left undisturbed. The pertinent situation is how long the article retains its condition. A really viscous fluid retains its shape for an hour although not more info a yr. A sound ought to keep its form lengthier 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 two these kinds of possible periodic arrangements. In Each and every, the initial layer has the atoms packed right into a airplane-triangular lattice in which every atom has 6 fast neighbours. Figure two shows this arrangement for the atoms labeled A

在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。

⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
