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。

There are actually a number of crystals dependant upon geometric structures, crystal advancement, and content. There is often arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid constructions.
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。
Ionic Crystals: Electrostatic forces kind ionic bonds. A typical illustration is a halite or salt crystal.
Q.four. What is the difference between atomic composition and crystal composition? Ans. The key difference between atomic framework and crystal framework lies in their definitions: atomic construction refers to how atoms are arranged in just a one molecule or a cluster of molecules, Whilst crystal construction fears website the particular arrangement of atoms in a solid material.

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 strains)。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」。
Crystals are categorized normally groups, including insulators, metals, semiconductors, and molecular solids. A single crystal of an insulator is often clear and resembles a piece of glass. Metals are shiny Except if they've rusted. Semiconductors are sometimes shiny and at times clear but are by no means rusty. Several crystals is usually labeled as a single type of stable, while some have intermediate behaviour. Cadmium sulfide (CdS) could be prepared in pure kind and is a superb insulator; when impurities are included to cadmium sulfide, it turns into a fascinating semiconductor.
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光,都可以在包裹体水晶种找到缩影。
