水晶原石观赏石充分体现了天然水晶的本质，经过抛光的水晶原石观赏石，玲珑剔透、晶莹璀璨，独具匠心的设计，恰到好处地显露出水晶的魅力。如果您想单纯的欣赏水晶，水晶原石观赏石是你的不二之选，给人一种返璞归真的感觉。

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。

Encyclopaedia Britannica's editors oversee issue locations during which they have got considerable know-how, whether or not from a long time of expertise gained by focusing on that material or through review for an advanced degree. They publish new content and confirm and edit material gained from contributors.

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。

发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。

根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?

市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。

The basic units of solids are both atoms or atoms that have put together into molecules. The electrons of the atom move in orbits that form a shell composition throughout the nucleus. The shells are filled in a scientific purchase, with Just about every shell accommodating only a small range of electrons. Different atoms have diverse figures of electrons, that happen to be dispersed inside of a attribute Digital framework of stuffed and partly more info filled shells.

水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体

crystal, any solid content where the element atoms are organized within a definite pattern and whose floor regularity displays its inner symmetry.
