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。

第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。

Binary crystals are found in a lot of structures. Some pairs of components variety multiple composition. At place temperature, cadmium sulfide might crystallize both 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 show various buildings at various temperatures. Amongst the most advanced crystals are People of silicon dioxide (SiO2), that has seven distinct structures at a variety of temperatures and pressures; more info the most typical of these constructions is quartz.
