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。
Large crystals of diamond are important gemstones. The crystal has other exciting Homes; it has the very best seem velocity of any strong and is the best conductor of heat. Besides diamond, one other typical form of carbon is graphite, and that is a layered product. Each and every carbon atom has a few coplanar near neighbours, forming an arrangement called the honeycomb lattice. A few-dimensional graphite crystals are obtained by stacking identical levels.
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。

包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
The definition of a good seems evident; a solid is normally regarded as staying difficult and business. Upon inspection, nonetheless, the definition results in being considerably less simple. A dice of butter, for instance, is hard right after being saved in the fridge and is Obviously a strong. Just after remaining within the kitchen counter for daily, exactly the same cube will become rather tender, and it truly is unclear In the event the butter need to nevertheless be regarded as a strong.
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
Molecular Crystals: Whole molecules are bonded to each other read more within an arranged manner. An excellent case in point is actually a sugar crystal, which has sucrose molecules.
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
Tetragonal �?Characterized by a few mutually perpendicular axes, two of that happen to be equivalent in size, even though the third is lengthier or shorter and perpendicular to the opposite two.
