对这类水晶晶簇观赏石的欣赏与评价，主要是强调晶体的完整、品种的名贵（如紫水晶、烟晶、发晶等）、造型奇特、含有名贵晶体（如辰砂、辉锑矿等）伴生等。晶簇产于矿床晶洞中，长相完美的并不多见，要完整无损地采集下来，又比较困难，故而采集起来代价较大，精品晶簇价值也就昂贵了。
A basic plan in crystal buildings may be the device mobile. It's the smallest unit of quantity that permits identical cells to become arranged collectively to occupy all accessible space. The geometrical basis of all crystals will be the lattice. A lattice may be seen as an everyday and infinite arrangement of details or atoms, where by Just about every place or atom has A similar bordering setting.
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。
If you want to see how crystals are shaped, it is possible to do a little job in your incredibly personal kitchen and see the formation in the crystals occur with your possess eyes . This may be finished by Placing a small volume of desk salt into some standard faucet water, hold out 24 hours, and you will see wonderful cubed formations. This happens as the drinking water is evaporating, which brings about the atoms that make up the salt (the mineral) along with the water to come back closer alongside one another.
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。
Encyclopaedia Britannica's editors oversee topic regions where they may have comprehensive expertise, regardless of whether from years of working experience attained by focusing on that articles or by using examine for an advanced degree. They produce new information and validate and edit material received from contributors.
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
Q.4. What is the distinction between atomic structure and crystal composition? Ans. The key distinction between atomic structure and crystal framework lies in their definitions: atomic framework refers to how atoms are structured inside a solitary molecule or simply a cluster of molecules, While crystal composition fears the precise arrangement of atoms inside a sound compound.
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
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。
You will discover only some unique device-mobile styles, so a variety of crystals share just one device-mobile sort. A very important characteristic of the device mobile is the number of atoms it consists of. The entire amount of atoms in your complete crystal is the variety in Each and every mobile multiplied by the volume of device cells. Copper and aluminum (Al) Just about check here every have just one atom for each unit mobile, although zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms for every unit mobile, but there are several exceptions. Crystals of polymers, for instance, have A huge number of atoms in Each and every unit cell.
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。
21You all know how any time you have a crystal prism and move a beam of sunlight through it, you can get a spectrum, which appears like a continual band of rainbow hues.
