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 stunning rock formations which have impressed individuals for Countless several years. They are useful for several various things, not only for decoration. Many of the to start with radios ever invented applied crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Specific properties and harmonic capabilities of crystals to generate highly exact measurements and adjustments.
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。

Crystal Lattices You will discover seven systems of crystal structures, that happen to be also called lattices or space lattices:
This Assessment chronicles over 20 years of research into developing a genetic code for crystal engineering. Rather then directing biological processes, this code works by using artificial forms of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which just about every facet of the resultant structures is usually systematically controlled. Inside this conceptual framework, the structural and functional developments are described in an effort to define the existing degree of sophistication and also to forecast future Instructions with the platform.
水晶观赏石是天然水晶中最具代表的作品，具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值，而水晶观赏石只需要将表面进行抛光，即展现出晶体内所包裹的物质，直接欣赏原汁原味的水晶石。
