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。
Another enjoyment, and delicious, experiment should be to kind significant crystals employing sugar. By heating sugar with water and after that allowing this Remedy evaporate on sticks, it is possible to sort rock candy from sugar crystals!
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：
The ordered interior structure of large crystals, such as fluorite and quartz shown in this article, is reflected in their geometric designs.
There are many different crystals based on geometric structures, crystal expansion, and substance. There is often arrangements of hexagonal carbon atoms or amethyst which makes hexagonal pyramid structures.
, has a similar framework, but There are 2 choices for selecting the holes which the atoms will occupy. The 3rd layer is often positioned in excess of the atoms of the main layer, producing an alternate layer sequence A
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
26Some of the best ingesting glasses are constructed from guide crystal.一些最精致的酒杯是用铅晶质玻璃制成的。《柯林斯英汉双解大词典》
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
A crystal program refers back to the classification of crystals determined by the geometric arrangement and symmetry of their lattice structures. You'll find seven principal crystal methods:
The essential units of solids are either atoms or atoms which have put together into get more info molecules. The electrons of the atom shift in orbits that form a shell framework around the nucleus. The shells are crammed in a scientific get, with Each individual shell accommodating only a small quantity of electrons. Various atoms have different numbers of electrons, which are distributed inside of a attribute Digital structure of crammed and partly filled shells.
The arrangement of an atom’s electrons determines its chemical Homes. The Qualities of solids are often predictable from the Attributes in their constituent atoms and molecules, and the different shell structures of atoms are for that reason to blame for the variety of solids.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
