Tetragonal: These crystals sort prisms and double pyramids. The structure is like a cubic crystal, other than a person axis is for a longer time than the other.
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。
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。
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
24I need to make my this means crystal crystal clear.我想把我的意思解释得清清楚楚。《牛津词典》
crystal The recently crystallized quartz grains are characterised by elongate crystals oriented oblique on the shear band margins, defining an average grain-form foliation. 来自 Cambridge English Corpus We are saying the chain topology inside the large w area acts as being the proverbial ' scratch-on-theglass ' essential in the organic and natural chemistry laboratory for making crystals. 来自 Cambridge English Corpus The age scatter between the person crystals may possibly reflect incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, often that contains inclusions of plagioclase microlaths and opaque phases.

Binary crystals are found in numerous structures. Some pairs of factors type multiple composition. At read more space temperature, cadmium sulfide may crystallize possibly from the zinc blende or wurtzite framework. Alumina also has two achievable buildings at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit unique constructions at distinct temperatures. Among the most complicated crystals are Individuals of silicon dioxide (SiO2), which has seven distinctive structures at different temperatures and pressures; the commonest of such buildings is quartz.
