17These rings are indicative in the crystal structure of nickel and can be stated only by invoking wavelike Houses of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
A elementary concept in crystal structures may be the unit cell. It is the smallest device of quantity that enables similar cells being organized jointly to occupy all obtainable Place. The geometrical basis of all crystals may be the lattice. A lattice may be viewed as a daily and infinite arrangement of details or atoms, wherever each issue or atom has An analogous surrounding ecosystem.
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。
诗中道出一段唐代由盛变衰的史实。玄宗末年，杨贵妃得宠，三姐妹并封为国夫人。他们养尊处优，奢华至极，仆人用水晶盘将珍馐佳肴端到宴席上，美人觉得没有口味，懒得动筷子。作为“诗圣”作为“史诗”，紫驼一段写饮食之精美，不空发议论，只尽情揭露事实，无一刺讥语，无一慨叹声，却使人于以外得之：此诗之善讽也。以史为鉴，这样的世道，这样的人物，国家不出“安史之乱”那样的大祸反倒不正常了。
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。
30Three times went previous, and I had been astonished to find out it once more: every one of the openings were being sewed up by slim and white thread and they appeared like the ice crystal on Wintertime's branches Crystal during the north.

幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
16I opened the box and observed a bit of crystal snowflake plus a greeting card with "Joyful Birthday" inside the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
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
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
Binary crystals are located in a lot of structures. Some pairs of things variety more than one framework. At place temperature, cadmium sulfide may perhaps crystallize possibly inside the zinc blende or wurtzite structure. Alumina also has two probable constructions at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals show diverse structures at distinctive temperatures. Among the many most complex crystals are All those of silicon dioxide (SiO2), which has seven different constructions at a variety of temperatures and pressures; the most common of such constructions is quartz.
