李商隐，杜牧，白居易，欧阳修，苏轼，呈大昌，辛弃疾，杨万里，吴文英，杨基，魏源等诗坛，词林大家都有歌吟水晶的佳篇传世。
③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。
These developments contain unique structures with programmable lattice symmetries and very well-defined crystal patterns, responsive supplies that leverage the intrinsic properties of nucleic acids to control buildings on need, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that provide insights into gentle–issue interactions. Hunting ahead, we challenge the Neighborhood to leverage the incredible structural Handle afforded by crystal engineering with DNA to synthesize classes of functional products that thrust past what has become attainable with naturally transpiring crystalline materials or Individuals created by much more common methods.
We've published about over three hundred stones during the mineral kingdom! Read about Each and every stone's exclusive origin, background, and energies underneath.
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。
Not all crystals form in water, but nearly all crystals type exactly the same way, atoms come alongside one another and turn into a uniformed cluster. The method can take as minor as a few days to possibly a thousand decades. All-natural crystals that come from the Earth sort precisely the same way.
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
There is a very similar directive about crystal glass which differentiates between total direct crystal, guide crystal and crystal.
Quite a few crystals behave like butter in that they are tough at minimal temperatures but soft at increased temperatures. They can be termed solids in the least temperatures down below their website melting level. A probable definition of a good is an object that retains its shape if left undisturbed. The pertinent problem is how long the thing retains its form. A hugely viscous fluid retains its condition for one hour but not a 12 months. A solid need to hold its form longer than that.
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。
看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
