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。

一般而言,紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅,颜色较深的为A级,稍浅的为B级。一般颜色较深的价格高,但要以不深暗为标准。颜色包括两种,一种是水晶本身的颜色,另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正,分布要均匀,不能太深或太浅,如澳州玉、蓝玉髓、紫晶、黄水晶,其价格就高。无色的水晶内含包裹体的颜色艳丽,其价格也高,如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。

看抛光:抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。

当二氧化硅结晶完美时就是水晶;结晶不完美的就是石英:二氧化硅胶化脱水后就是玛瑙;二氧化硅含水的胶体凝固后就成为蛋白石;二氧化硅晶粒小于几微米时,就组成玉髓、燧石、次生石英岩。

Crystals are almost nothing in excess of an ordered arrangement of molecules or atoms. Crystals can be found in numerous shapes and sizes, and each has distinct traits. Whatever they are made of decides how it will eventually kind.

水晶是有成色等级之分,影响水晶价位的因素很多,不像钻石以4C就可以判定,所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好,越透越好,颜色越娇嫩越好,形状越典型越好。不过最重要还是自己喜欢,而选购时辨识真伪的方法大致有下列几种:

There are other minerals and molecules that will kind these crystal lattices. Snowflakes certainly are a common example of a about symmetric and geometrically patterned construction from ice crystals, and gemstones of all varieties are generally crystals.

水玉:中国最古老的称法叫水玉,意谓似水之玉,又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道:�?水玉簪头白角巾,瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》:�?又东三百里,日堂庭之�?…�?多水�?”;�?丹山出焉,东南流注于洛水,其中多水玉 ”;�?逐水出焉,北流注于渭,其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉,古人是看�?�?其莹如水,其坚如�?�?的质地。

Yet another form of crystalline carbon is based on the molecule with 60 carbon atoms named buckminsterfullerene (C60). The molecular condition is spherical. Each and every carbon is bonded to a few neighbours, as in graphite, and the spherical form is realized by a mix of twelve rings with 5 sides and 20 rings with six sides. Very similar constructions had been initial visualized with the American architect R. Buckminster Fuller for click here geodesic domes.
