23Sometimes, having said that, the crystal kind of the silicate inclusions is noticed to resemble additional carefully The inner construction of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
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。
Huge crystals of diamond are valuable gemstones. The crystal has other interesting Qualities; it has the best seem velocity of any strong and is the best conductor of warmth. Besides diamond, the other popular method of carbon is graphite, that is a layered product. Every single carbon atom has a few coplanar around neighbours, forming an arrangement known as the honeycomb lattice. A few-dimensional graphite crystals are attained by stacking very similar levels.
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。
Encyclopaedia Britannica's editors oversee subject matter parts wherein they may have comprehensive know-how, whether or not from yrs of working experience acquired by focusing on that articles or through review for a sophisticated degree.

水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
The definition of the good appears evident; a reliable is mostly thought of as being challenging get more info and organization. On inspection, however, the definition results in being significantly less uncomplicated. A dice of butter, for example, is tough just after staying saved inside a refrigerator which is Plainly a good.

The sodium chloride crystal lattice is characterized from the close packing in the beneficial sodium ions and destructive chloride ions. Each sodium ion is surrounded by 6 chloride ions, and each chloride ion is surrounded by six sodium ions, developing a hugely stable and symmetrical composition.
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
