晶及其石英岩类玉石是中低档宝玉石,虽比不上钻石、红蓝宝石的高贵,但在加工中如果构思巧妙而且加工精细,同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
养殖晶:养殖晶是指,用天然水晶做种子,然后赋予天然水晶生长的高压条件,养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长,这样的水晶成分(分子式)与天然水晶是一摸一样的,唯一有差别的是,这样的水晶磁场作用没有天然水晶强。

水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见,所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人,所以通常人们会要求水晶净度越高越好,尽量避免有较明显的内含物的水晶。
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。
Q.four. Exactly what is the distinction between atomic construction and crystal structure? Ans.

The C60 molecules, also called buckyballs, are quite strong and Virtually incompressible. Crystals are shaped such the balls are arranged within an fcc lattice with a 1-nanometre spacing in between the centres of adjacent balls. The very similar C70 molecule has The form of the rugby ball; C70 molecules also variety an fcc crystal when stacked with each other. The stable fullerenes variety molecular crystals, with weak binding—supplied by van der Waals interactions—amongst the molecules.
