Not all crystals are Similarly crystalline. There are sometimes impurities, and also the ionic & covalent among molecules can build vastly different buildings from the identical material. A great illustration of this are diamonds and graphene.
23Sometimes, nevertheless, the crystal type of the silicate inclusions is noticed to resemble more carefully The interior composition 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。
景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。
The ordered inner framework of huge crystals, such as fluorite and quartz revealed below, is reflected within their geometric shapes.
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
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。
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。

Crystals are sometimes viewed as anything of immense elegance, and they are generally utilized with diamonds or other stones to generate pieces of jewellery. Many crystals now are man-produced in laboratories.
The definition of the strong appears clear; a sound is normally considered remaining challenging and agency. Upon inspection, however, the definition results in being less clear-cut. A dice of butter, for example, is tough following becoming stored in a fridge which is Obviously a sound. Immediately after remaining over the kitchen counter for every day, more info the exact same cube turns into very comfortable, and it is actually unclear In the event the butter need to however be viewed as a stable.
. The second layer is shaded in the determine. It's got the exact same plane-triangular composition; the atoms sit in the holes fashioned by the primary layer. The initial layer has two equal sets of holes, though the atoms of the second layer can occupy just one established. The third layer, labeled C
Molecular Crystals: Overall molecules are bonded to each other within an organized fashion. A fantastic case in point is a sugar crystal, which includes sucrose molecules.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
A further form of crystalline carbon relies with a molecule with 60 carbon atoms known as buckminsterfullerene (C60). The molecular condition is spherical. Each individual carbon is bonded to a few neighbours, as in graphite, as well as the spherical condition is reached by a mixture of 12 rings with 5 sides and twenty rings with six sides. Comparable constructions were being initially visualized through the American architect R. Buckminster Fuller for geodesic domes.
