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。
23Sometimes, nonetheless, the crystal form of the silicate inclusions is observed to resemble more intently The inner composition of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。
These developments consist of exotic buildings with programmable lattice symmetries and properly-described crystal routines, responsive elements that leverage the intrinsic Homes of nucleic acids to manipulate constructions on demand, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals which provide insights into light–issue interactions. Hunting ahead, we obstacle the Local community to leverage the incredible structural Handle afforded by crystal engineering with DNA to synthesize courses of functional materials that force past what is achievable with naturally happening crystalline supplies or These created by a lot more regular approaches.
Most strong products found in mother nature exist in polycrystalline variety as opposed to as a single crystal. They are actually made up of millions of grains (modest crystals) packed together to fill all Place. Each and every unique grain has a distinct orientation than its neighbours. Though prolonged-variety order exists in just one grain, for the boundary amongst grains, the buying variations way. A typical bit of iron or copper (Cu) is polycrystalline.
看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。
Monoclinic �?Characterized by three unequal axes, two of which intersect at an oblique angle, though the 3rd is perpendicular for the aircraft of one other two.
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。
Crystals are very little over an requested arrangement of molecules or atoms. Crystals come in many alternative shapes and sizes, and each has distinct traits. Whatever they are made of determines how it is going to variety.
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。

Crystals are not just renowned for their physical physical appearance, but unique crystals of various products and formations can lead to an enormous a number of takes advantage of and Actual physical Attributes.
⑦双色水晶：一种紫色和黄色共存一体的水晶，紫色、黄色之间界限较明显，分别占据晶块的一部分。
Binary crystals are present in quite a few constructions. Some pairs of elements type multiple framework. At home temperature, cadmium sulfide may crystallize both while in the zinc blende or wurtzite construction. Alumina also has two achievable buildings at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit various buildings at different temperatures. Among the most intricate crystals are those of silicon dioxide (SiO2), that has 7 various constructions at different temperatures and pressures; read more the most typical of these structures is quartz.
