This concept applies equally in a single, two, and 3-dimensional Areas. The whole crystal lattice is often manufactured by continuously reproducing the sample of the device mobile in all Instructions.

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。

水碧:《山海经》中,水晶又被称作水碧: �?又南三百里,日耿山,无草木,多水碧 �?,郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用,晋代郭景纯《璞江赋》道�?�?鬼,水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉,水精谓之玉瑛也�?”

这种水晶观赏石特指水晶晶簇,它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。

Lattices could possibly have one lattice place for every cell or multiple, yielding a complete of fourteen Bravais crystal lattice varieties. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array created by a list of discrete details.

The elements are discovered in a variety of crystal packing arrangements. The commonest lattice structures for metals are Individuals acquired by stacking the atomic spheres into the most compact arrangement.

广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。

水晶的价值还与块体大小有关,同样的颜色和净度级别,块越大越难得。有时候质量级别虽然低一些,但块体够大,也可能价格高于高级别的小晶体

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。

水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手,但好的水晶一般大家都想得到,值与不值,就要看经验了。由于天然水晶的开采和制作原因,没有瑕疵的水晶很难得到,纯净的饰品要达到与合成水晶媲美的品质,实在是很难得。另外,由于水晶的特性,在佩戴过程中,也会改变其等级,比如因为某种原因,有可能会逐渐产生较大裂纹。
