Calcite crystals are sometimes Employed in optical equipment, and in many cases the graphite in pencil guide are sheets of crystals that basically break apart layer by layer to write. Silica can kind silicate crystals which can be The idea for quartz, mica, olivine, and many other crystals and minerals.
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
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。
There are numerous crystals dependant upon geometric constructions, crystal progress, and product. There could be arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid structures.
Monoclinic �?Characterised by three unequal axes, two of which intersect at an oblique angle, whilst the third is perpendicular on the airplane of the opposite two.
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
There's a related directive about crystal glass which differentiates involving comprehensive direct crystal, guide crystal and crystal.
Numerous crystals behave like butter in that they're difficult at small temperatures but comfortable at bigger temperatures. They may be termed solids in the least temperatures down below their melting issue. A doable definition of the stable is really an item that retains its shape if remaining undisturbed. The pertinent situation is how much time the thing retains its condition. A check here really viscous fluid retains its condition for one hour but not a 12 months. A sound should preserve its condition for a longer time than that.
Crystals with apparent flat faces are named euhedral crystals, while These missing outlined faces are termed anhedral crystals. Crystals consisting of ordered arrays of atoms that are not generally periodic are named quasicrystals.
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
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（growth 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」。
14For example, We've Quartz crystal clocks and watches exact to within just a person minute a yr.例如，我们使用的每年误差不超过1分钟的石英水晶钟表和手表。
Binary crystals are found in quite a few buildings. Some pairs of things type more than one framework. At area temperature, cadmium sulfide could crystallize both while in the zinc blende or wurtzite construction. Alumina also has two feasible structures at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit unique buildings at distinctive temperatures. Amongst the most advanced crystals are These of silicon dioxide (SiO2), which has 7 distinct structures at several temperatures and pressures; the most common of those buildings is quartz.
