A different pleasurable, and tasty, experiment should be to type big crystals applying sugar. By heating sugar with drinking water and afterwards permitting this solution evaporate on sticks, you could form rock sweet from sugar crystals!
对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

How Crystals Variety The entire process of forming a crystal is named crystallization. Crystallization normally happens whenever a stable crystal grows from the liquid or Option.
Lattices may have a person lattice position for every cell or more than one, yielding a total of fourteen Bravais crystal lattice styles. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array produced by a set of discrete details.
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
