轴性、光性：一轴晶正光性。正交偏光下所看到的一轴晶干涉图是独特的，其黑十字臂未达中心，形成中空的图案，俗称牛眼干涉图。中心部分通常为淡绿色或淡粉色。

无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。
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。
You will find a identical directive about crystal glass which differentiates among complete lead crystal, guide crystal and crystal.
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
The definition of a good appears noticeable; a sound is generally considered staying tough and firm. On inspection, nevertheless, the definition results in being significantly less easy. A dice of butter, one example is, is hard immediately after becoming stored in a refrigerator and it is clearly a strong. Following remaining on the kitchen counter for on a daily basis, the identical dice becomes very comfortable, and it is unclear In case the butter really should still be regarded as a good.
say cheese something which somebody who is having a photograph of you tells you to say so that the mouth tends to make The form of a smile
There are actually other minerals and molecules which can variety these crystal lattices. Snowflakes certainly are a basic illustration of a about symmetric and geometrically patterned framework from ice crystals, and gemstones of all versions are generally crystals.
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
crystal Alteration is variable: absent in lots of crystals, in Many others creating dense sericite aggregates which can clearly show some recrystallization more info results to create coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are occasionally organized in aggregates. From your Cambridge English Corpus Moreover, haloarchaeal cells ended up embedded in salt crystals below laboratory circumstances and subsequently analysed by light-weight microscopy. Through the Cambridge English Corpus The white clouds (commonly sparse) have been also broadly considered to be remaining composed of tiny crystals of h2o ice, relatively like cirrus within our environment. Within the Cambridge English Corpus These are found in evaporite salt lakes and might be trapped in salt crystals for the duration of evaporation. Within the Cambridge English Corpus As a result, the cells (organelles and membranes) are ruined mechanically by ice crystals, resulting in Dying through cell lysis. In the Cambridge English Corpus The crystals were Utilized in the primary or 2nd orders of reflection. Within the Cambridge English Corpus In our 8xperiments, the crystals were cubes using a foundation place of 8 e mm. In the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and stress.
