The Basic Principles Of Crystal

看颜色:即使在同一种类的水晶中,它的不同部位的纹理、色泽也各式各有千秋。属于单色的,要色度均匀;在同一块水晶上有深浅的,则要求其色调纹路美观大方。

按照透明度指标,水晶越透明,价格越高,好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽,否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明,可有较多裂纹。三者价值依次降低,熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中,晶体较大的,可用来做水晶眼镜和雕刻高档工艺品,因而价格较高。

人造水晶分为熔炼水晶与养殖晶:据水晶专家汪毅的阐述,随着水晶的价值提高,喜欢的人增多,水晶也引起了作伪者的兴趣,现阶段中国水晶市场常见的造假方法为:

养殖晶:养殖晶是指,用天然水晶做种子,然后赋予天然水晶生长的高压条件,养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长,这样的水晶成分(分子式)与天然水晶是一摸一样的,唯一有差别的是,这样的水晶磁场作用没有天然水晶强。

水晶原石观赏石,从字面意义理解:观赏水晶石的原貌,即经过抛光去皮后的包裹体水晶和原色水晶,不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高,水晶晶体通透干净,颜色艳丽,意境鲜明深刻的价值就高,它的价值特点就好比钻石,实实在在石头本身的价值。

水晶常以晶簇、晶洞形式产出,其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙,当富含硅质矿物的流体进入较薄的熔岩孔隙中,且温、压条件合适时将结晶沉淀出水晶等矿物。

晶体 Silicon crystals developed in a very laboratory change gentle into electrical Strength. 在实验室中长成的硅晶体可将光线转变为电能。

The essential units of solids are possibly atoms or atoms which have blended into molecules. The electrons of the atom transfer in orbits that sort a shell structure throughout the nucleus. The shells are crammed in a scientific order, with Just about every shell accommodating only a small number of electrons. Distinct atoms have distinct numbers of electrons, which can be distributed in the attribute Digital framework of loaded and partly loaded shells.

The sodium chloride crystal lattice is characterised because of the near packing from the favourable sodium ions and unfavorable chloride ions. Each sodium ion is surrounded by 6 chloride ions, and every chloride ion is surrounded by six sodium ions, developing a hugely secure and symmetrical construction.

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。
