看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
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。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
You can find a variety of crystals dependant upon geometric structures, crystal progress, and content. There may be preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid structures.
They can ultimately produce a wonderful very little uniform cluster of atoms, This can be the whole process of expanding crystals. The more they might come alongside one another, the greater of the development is going to be noticeable towards the naked eye. Experts can decide what mineral They can be looking at by how the crystals variety.
30Three days went past, and I had been astonished to discover it yet again: every one of the openings were being sewed up by slim and white thread and they appeared such as the ice crystal on Wintertime's branches inside the north.
Crystals can be grown less than average situations from all ninety two naturally transpiring aspects except helium, and helium is usually crystallized at minimal temperatures by using 25 atmospheres of pressure.
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
crystal The recently crystallized quartz grains are characterised by elongate crystals oriented oblique to your shear band margins, defining a typical grain-form foliation. 来自 Cambridge English Corpus We are saying the chain topology within the substantial w area acts as being the proverbial ' scratch-on-theglass ' required while in more info the natural and organic chemistry laboratory to generate crystals. 来自 Cambridge English Corpus The age scatter between the person crystals could mirror incorporation of xenocrysts from previously magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, once in a while made up of inclusions of plagioclase microlaths and opaque phases.
16I opened the box and noticed a piece of crystal snowflake plus a greeting card with "Joyful Birthday" during the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（development lines）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
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。
One more type of crystalline carbon is predicated on a molecule with 60 carbon atoms termed buckminsterfullerene (C60). The molecular shape is spherical. Each individual carbon is bonded to three neighbours, as in graphite, plus the spherical condition is reached by a mix of 12 rings with five sides and 20 rings with six sides. Similar constructions ended up first visualized through the American architect R. Buckminster Fuller for geodesic domes.
