无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度,越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏,就没有利用价值。

水晶文化历史悠久,古人曾赋予它一串极富美感的雅称:水玉、水精、水碧、石英等。

Tetragonal: These crystals kind prisms and double pyramids. The composition is like a cubic crystal, other than just one axis is for a longer period than the opposite.

You will discover many various crystals depending on geometric buildings, crystal advancement, and content. There may be arrangements of hexagonal carbon atoms or amethyst which makes hexagonal pyramid constructions.

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。

石英:《广雅》称水晶叫石英,色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释:�?�?,白石英�?”。

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。

水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹,这种裂纹有大有小,对水晶的影响也有大小之分。

在透明的水晶中,隐裂纹呈亮晶晶的片状,有时还会有晕彩效应。这些裂纹是水晶在生长过程中,遇到外力挤压而在内部产生的一些隐形裂纹,隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充,形成愈合的裂纹,也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
