The requested internal construction of large crystals, just like the fluorite and quartz shown in this article, is reflected within their geometric designs.
水胆水晶,包括气态,液态,固态,有时候可以同时多态并存,无色居多,个别情况下可见红色,绿色,黄色,蓝色,黑色等。

Solids which have shorter-range get but deficiency lengthy-assortment get are known as amorphous. Pretty much any product is usually built amorphous by rapid solidification from the melt (molten state). This issue is unstable, along with the strong will crystallize in time. If your timescale for crystallization is yrs, then the amorphous condition appears secure.
⑥、丝印:水晶表面附有不同的色料进行效果处理,颜色层面较厚,着力后方可脱落。
Orthorhombic: They're rhombic prisms and dipyramids that resemble tetragons but without square cross-sections.
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。
