天然的水晶一般都会有絮状(绵绺),也就是大家俗称的瑕疵,这是液体水落石出和二氧化碳的小孔穴,而人工合成的水晶就不会有这样的特征。

③、粗抛光:是将模具压出之毛胚,以金刚石盘直接磨出成品之刻线。④、细抛光:在粗抛光之后,以抛光粉来磨成品至晶莹剔透为止。

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。

Crystalline construction is characterized by a geometrical, repeating sample of symmetric molecular structure. The arrangement of atoms sorts these purchased, repeating designs.

Lattices might have one particular lattice stage for each cell or more than one, yielding a complete of fourteen Bravais crystal lattice varieties. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array created by a set of discrete points.

对任何宝石来说,颜色都是非常重要的,水晶也不例外。如果是水晶晶体是有颜色的,如粉水晶、黄水晶、紫水晶等,其颜色评价的最高标准则是明艳动人,不带有灰色、黑色、褐色等其他色调。如粉水晶,颜色以粉红为佳;紫水晶,要求颜色为鲜紫,纯净不发黑;黄水晶,要求颜色不含绿色、柠檬色调,以金橘色为佳。对于发晶来说,晶体的颜色也是很重要的。相同发丝的金发晶,晶体完全无色(白水晶)和晶体略偏茶色,肉眼的视觉观感也是有差别的,所以前者的价格会高于后者。

如果水晶内部杂质中有传说中人物的造型,如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。

Among the many binary crystals, the easiest structures to visualize are Individuals with equivalent quantities of the two varieties of atoms. The structure of sodium chloride is based on a dice. To assemble the lattice, the sodium and chlorine atoms are put on alternate corners of the dice, as well as composition is recurring (Figure click here 3B).

⑤化学稳定�?非常好,在常温下仅溶解于氢氟酸,不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。

15The trick to a very good thermoelectric materials is usually a crystal construction wherein electrons can circulation 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。

玉石纹理如果能形成美丽的花纹、图案,其价格就高,如玛瑙内红白相间的色带有规律地排列,形成缠丝玛瑙时,碧玉中的不均匀颜色形成一种风景图案时,材料的价值将提高。当水晶内包裹体形成美丽的图案时,如幽灵水晶、风景水晶,或者针状包裹体呈束状排列时,其价值都高于普通的水晶。图案越美观、越有意境越好。
