诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇还有：

the reliable state of numerous easy substances, which have an everyday shape and surfaces arranged in equivalent styles

景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。

Tetragonal: These crystals type prisms and double pyramids. The framework is like a cubic crystal, besides one axis is for a longer period than the other.

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。

发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。

30Three days went previous, and I had been astonished to view it again: the many openings ended up sewed up by slim and white thread and they seemed like the ice crystal on Winter season's branches within the north.

②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。

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。

颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。

地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。

You will discover other minerals and molecules that could type these crystal lattices. Snowflakes are a vintage example of a approximately symmetric and geometrically patterned framework from ice crystals, and gemstones of all types are more info generally crystals.

This Assessment chronicles about two decades of investigation into developing a genetic code for crystal engineering. As an alternative to directing biological processes, this code takes advantage of artificial forms of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which almost just about every aspect of the resultant structures may be systematically managed. Inside of this conceptual framework, the structural and useful developments are described in order to determine the current amount of sophistication and to forecast upcoming Instructions with the System.

⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
