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。

Crystals are wonderful rock formations that have surprised individuals for Many decades. They are used for quite a few different things, not just for decoration.

This Overview chronicles in excess of two decades of research into developing a genetic code for crystal engineering. As an alternative to directing biological procedures, this code uses synthetic kinds of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which just about each element of the resultant structures might be systematically managed. In just this conceptual framework, the structural and useful developments are described in an effort to define the present amount of sophistication and also to forecast potential Instructions from the platform.
