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。

无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。

These innovations consist of exotic buildings with programmable lattice symmetries and effectively-outlined crystal patterns, responsive resources that leverage the intrinsic Qualities of nucleic acids to manipulate buildings on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals which offer insights into light-weight–make a difference interactions. Seeking ahead, we obstacle the Neighborhood to leverage the extraordinary structural Command afforded by crystal engineering with DNA to synthesize classes of practical resources that drive over and above what has actually been doable with Normally taking place crystalline materials or People produced by more conventional methods.

Fig. 7: A template-directed approach can Command the placement of developing blocks over a surface in the development of complicated constructions.

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。

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。

Amongst the binary crystals, the best more info constructions to visualize are All those with equal figures of the two sorts of atoms. The structure of sodium chloride relies over a dice. To build the lattice, the sodium and chlorine atoms are put on alternate corners of a cube, as well as framework is repeated (Determine 3B).

⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。

15The trick to a superb thermoelectric material is really a crystal construction during which electrons can stream freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。

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。
