其它描述:《庶物异名疏》中说: �?水精出大秦国,一名黎�?�?。结晶完整的水晶晶体,就如参差交错的马齿,所以人们又叫它马牙石。先民们最早用它研磨成眼镜片,因而送它一个眼镜石的绰号。水晶有通称,也有俗称。广州一带称水晶叫晶玉,又名鱼脑冻;江苏东海县山民发现水晶会 �?窜火�?�?,于是给它起个放光石的俗名。世间一物多名,不足为奇,而像水晶拥有这么多的别称,实不多见。瞧,从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等,简直构成一部奇石鉴赏史。

A essential concept in crystal buildings could be the device mobile. It is the smallest device of volume that enables identical cells for being organized alongside one another to occupy all obtainable Place. The geometrical foundation of all crystals could be the lattice. A lattice is often seen as a daily and infinite arrangement of points or atoms, the place Each individual issue or atom has The same encompassing setting.

4Without a crystal ball, It is really unachievable to say wherever we'll be next year.不用水晶球预卜未来,我们说不准明年处境如何呀。《牛津词典》

The purchased inner structure of large crystals, just like the fluorite and quartz demonstrated here, is reflected in their geometric styles.

You will also find a lot of products that resemble crystals but are actually polycrystals. Polycrystals type when microscopic crystals fuse jointly to type a stable. These supplies will not include requested lattices.

Lattices can have one lattice level for each cell or more than one, yielding a total of fourteen Bravais crystal lattice varieties. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the 3-dimensional array made 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。

发晶:无色、浅黄、浅褐等,可因含金红石常呈金黄、褐红等色,含电气石常呈灰黑色;含阳起石而呈灰绿色。

仿制钛晶树水晶:钛晶是水晶里价格最昂贵的,造假者当然也不会放过这么好的产品。天然的环境下,在水晶里能生长个像树一样的钛晶,完全是可能的,只是这样的货很少,那我们的造假专家是如何做的呢,白水晶底下打个洞,激光打点成板状的钛晶进去,就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面,会采用将钛晶部位割成板状,与圆面的水晶粘合的方法来制作。

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。

The arrangement of an atom’s electrons decides its chemical Homes. The click here properties of solids are usually predictable within the Houses of their constituent atoms and molecules, and the several shell constructions of atoms are for that reason accountable for the variety of solids.

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。

水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光,都可以在包裹体水晶种找到缩影。
