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:
23Sometimes, nevertheless, the crystal form of the silicate inclusions is noticed to resemble extra intently The interior 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。
Chemical Bonds The types of chemical bonds formed in between atoms or teams of atoms in crystals rely upon their sizing and electronegativity. You can find four groups of crystals as grouped by their bonding:
Massive crystals of diamond are useful gemstones. The crystal has other appealing Attributes; it has the best sound velocity of any good and is the best conductor of heat. In addition to diamond, the opposite typical kind of carbon is graphite, which is a layered substance. Each carbon atom has a few coplanar close to neighbours, forming an arrangement called the honeycomb lattice. Three-dimensional graphite crystals are obtained by stacking related levels.
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。
你们都知道,拿起一个水晶棱镜,让一束阳光通过它,就会得到一个光谱,看起来就像一条连续的彩虹色带。
⑩、雷射内雕:以计算机辅助激光设备在水晶对象中进行三维图案的成型,艺术效果好,可以任意表达各类图案,图形,达到逼真效果
发晶:无色、浅黄、浅褐等,可因含金红石常呈金黄、褐红等色,含电气石常呈灰黑色;含阳起石而呈灰绿色。
第三种是“皮景”,因某些其他的矿物与水晶体共生,或由于其他的物质侵蚀而依附于水晶表面,或者是水晶受自然环境的影响,在水晶表面出现蚀象,形成了一些景象或图案,这种景观存在于水晶表面。
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
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”。
You can more info find other minerals and molecules which can form these crystal lattices. Snowflakes certainly are a typical example of a around symmetric and geometrically patterned construction from ice crystals, and gemstones of all versions are typically crystals.
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。
矿物成分:针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶,如发晶、钛晶、绿幽灵等,发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶;含铁�?;呈金黄色或柠檬�?)称黄水晶;含锰和钛呈玫瑰色者称蔷薇石英,即粉水晶;烟色者称烟水晶;褐色者称茶晶;黑色透明者称为墨晶。
