水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

水晶原石观赏石充分体现了天然水晶的本质，经过抛光的水晶原石观赏石，玲珑剔透、晶莹璀璨，独具匠心的设计，恰到好处地显露出水晶的魅力。如果您想单纯的欣赏水晶，水晶原石观赏石是你的不二之选，给人一种返璞归真的感觉。

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。

Encyclopaedia Britannica's editors oversee matter spots where they have intensive understanding, whether from years of knowledge acquired by focusing on that content material or by way of analyze for a sophisticated degree. They generate new articles and validate and edit articles been given from contributors.

Fig. 4: Creating blocks with different shapes and area chemistries immediate the formation of unique crystal symmetries.

⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。

水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。

Hexagonal �?Characterized by four axes, 3 of which are equivalent in length and intersect at one hundred twenty levels, which has a fourth axis perpendicular to the other three.

Meanwhile, to guarantee ongoing assist, we have been displaying the positioning with out models and JavaScript.

Solids that have shorter-variety purchase but absence long-selection purchase are referred to as amorphous. Just about any substance might be built amorphous by quick solidification from the soften (molten condition). This condition is unstable, and also the good will crystallize in time. When the timescale for crystallization is several years, then the amorphous state seems stable.

Orthorhombic: These are generally 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。

Binary crystals are present in numerous constructions. Some pairs of aspects variety multiple construction. At space temperature, cadmium sulfide may possibly crystallize both while in the zinc blende or wurtzite structure. Alumina also has two feasible structures at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit various buildings at diverse temperatures. Amongst check here the most complicated crystals are Those people of silicon dioxide (SiO2), that has 7 unique constructions at a variety of temperatures and pressures; the most typical of these structures is quartz.
