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。
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
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 requested inner composition of huge crystals, such as fluorite and quartz demonstrated listed here, 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。
They're going to inevitably generate a good tiny uniform cluster of atoms, That is the entire process of rising crystals. The greater they are able to arrive with each other, the more of a formation are going to be visible towards the bare eye. Experts can ascertain what mineral They're thinking about by how the crystals type.
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。
Ionic Crystals: Electrostatic forces sort ionic bonds. A typical illustration is usually a halite or salt crystal.
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 the strong seems apparent; a strong is generally regarded as being really hard and firm. On inspection, however, the definition will become less uncomplicated. A cube of butter, by way of example, is hard soon after remaining saved inside a refrigerator and is particularly Plainly a good. Right after remaining around the kitchen area counter for a day, exactly the same cube becomes quite tender, and it really is unclear Should the butter ought to continue to be considered a solid.
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。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
A further kind of crystalline carbon is predicated on the molecule with 60 carbon atoms identified as buckminsterfullerene (C60). The molecular condition is spherical. Each and every carbon is bonded to 3 neighbours, as in graphite, as well as the spherical form is realized by a mixture of 12 rings with 5 sides and twenty rings with read more six sides. Comparable constructions were very first visualized because of the American architect R. Buckminster Fuller for geodesic domes.
