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。
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。
发晶的价值取决于发的颜色、罕见性及大小，一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态，便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值，通过它们可了解几百万年前地球上水的成分及变化。
Most solid resources located in nature exist in polycrystalline form in lieu of as one crystal. They are actually composed of an incredible number of grains (smaller crystals) packed with each other to fill all Place. Every single particular person grain has a unique orientation than its neighbours. Despite the fact that very long-array get exists inside just one grain, in the boundary involving grains, the buying modifications direction. A standard bit of iron or copper (Cu) is polycrystalline.
You will find numerous crystals depending on geometric structures, crystal development, and materials. There might be arrangements of hexagonal carbon atoms or amethyst which makes hexagonal pyramid constructions.
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。
Crystals look exceptional from all kinds of other rocks and minerals, but �?barring some Unique scenarios �?almost all minerals hide a crystalline construction underneath the area.

仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
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。
Crystal Lattices You will discover seven methods of crystal buildings, that happen Crystal to be also referred to as lattices or space lattices:
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。
crystal Alteration is variable: absent in several crystals, in Many others producing dense sericite aggregates which can exhibit some recrystallization outcomes to create coarser-grained white mica. From your Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes organized in aggregates. In the Cambridge English Corpus In addition, haloarchaeal cells were being embedded in salt crystals below laboratory disorders and subsequently analysed by gentle microscopy. From your Cambridge English Corpus The white clouds (generally sparse) were also broadly regarded as becoming made up of little crystals of water ice, fairly like cirrus in our atmosphere. Through the Cambridge English Corpus They are present in evaporite salt lakes and might be trapped in salt crystals in the course of evaporation. In the Cambridge English Corpus As a result, the cells (organelles and membranes) are ruined mechanically by ice crystals, bringing about Dying via cell lysis. Through the Cambridge English Corpus The crystals were Utilized in the primary or 2nd orders of reflection. With the Cambridge English Corpus Inside our 8xperiments, the crystals ended up cubes that has a foundation area of 8 e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : impact of temperature and strain.
