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。
Bismuth (Bi) seems being a steel, but the volume of electrons obtainable for electrical conduction is analogous to that of semiconductors. Actually, bismuth is known as a semimetal. Molecular solids are often crystals shaped from molecules or polymers. They can be insulating, semiconducting, or metallic, with regards to the form of molecules from the crystal. New molecules are constantly currently being synthesized, and plenty of are made into crystals. The quantity of diverse crystals is big.
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
诗中道出一段唐代由盛变衰的史实。玄宗末年，杨贵妃得宠，三姐妹并封为国夫人。他们养尊处优，奢华至极，仆人用水晶盘将珍馐佳肴端到宴席上，美人觉得没有口味，懒得动筷子。作为“诗圣”作为“史诗”，紫驼一段写饮食之精美，不空发议论，只尽情揭露事实，无一刺讥语，无一慨叹声，却使人于以外得之：此诗之善讽也。以史为鉴，这样的世道，这样的人物，国家不出“安史之乱”那样的大祸反倒不正常了。
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
Learn the way the shape on the crystals determine the several minerals into familiesMinerals crystallize according to one among seven motifs, often known as crystal units.
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。

Among the many binary crystals, the best constructions to visualise are Individuals with equal quantities of The 2 types of atoms. The construction of sodium chloride relies on a dice. To assemble the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, as well as the structure is recurring (Determine click here 3B).
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
15The trick to a superb thermoelectric materials is usually a crystal structure where electrons can movement 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。
Fig. one: Schematic of crystal formation from creating blocks made up of a particle Main in addition to a shell of DNA ligands connected to the particle surface area.
This Evaluation chronicles about two decades of research into making a genetic code for crystal engineering. Rather then directing Organic processes, this code works by using synthetic varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which nearly each and every aspect of the resultant constructions can be systematically controlled. In this conceptual framework, the structural and functional advances are explained in order to outline the present level of sophistication and to forecast foreseeable future directions with the System.
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
