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。

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。

A crystal framework concentrates on how the atoms are arranged inside the crystal. Having said that, crystallographers have an interest in the general form and dimensions in the crystal in addition to its exterior characteristics. To accomplish this, they should understand about the crystal program.

We have published about around three hundred stones in the mineral kingdom! Read about Every single stone's distinctive origin, historical past, and energies beneath.

There are numerous crystals based upon geometric constructions, crystal growth, and product. There could be arrangements of hexagonal carbon atoms or amethyst that makes hexagonal pyramid structures.

结晶�?When sea h2o is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。

Crystals look special from many other rocks and minerals, but �?barring a couple of Unique cases �?almost all minerals disguise a crystalline structure beneath the surface area.

11I very carefully opened the offer and located a crystal bell inside.我小心地打开包裹，发现里面有一个水晶钟。

Crystals are often considered as one thing of enormous splendor, plus they are generally employed with diamonds or other stones for making items of jewellery. Nearly all of crystals now are man-manufactured in laboratories.

Solids which have quick-variety purchase but lack very long-vary order are termed amorphous. Just about any material is usually produced amorphous by fast solidification in the melt (molten condition). This condition is unstable, as well as the reliable will crystallize in time. If the timescale for crystallization is yrs, then the amorphous condition appears steady.

Orthorhombic: They are rhombic prisms and dipyramids that resemble tetragons but without having sq. cross-sections.

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 present in a lot of structures. Some pairs of features kind more than one composition. At place temperature, cadmium sulfide check here may perhaps crystallize both from the zinc blende or wurtzite construction. Alumina also has two feasible buildings at home temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinctive structures at unique temperatures. One of the most complex crystals are People of silicon dioxide (SiO2), which has seven distinctive structures at several temperatures and pressures; the commonest of such constructions is quartz.
