天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。

Bismuth (Bi) appears for being a metal, but the number of electrons accessible for electrical conduction is comparable to that of semiconductors. In fact, bismuth known as a semimetal. Molecular solids usually are crystals shaped from molecules or polymers. They may be insulating, semiconducting, or metallic, depending upon the kind of molecules during the crystal. New molecules are constantly being synthesized, and many are made into crystals. The quantity of distinctive crystals is enormous.

4Without a crystal ball, It is really unattainable to mention exactly where we are going to be upcoming year.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》

We have created about about 300 stones from the mineral kingdom! Read about Each and every stone's exclusive origin, background, and energies below.

看抛光：抛光的好坏直接影响到水晶制品的身价。抛光分为软抛光与硬抛光。

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

Springer Mother nature continues to be neutral with regards to jurisdictional statements in published maps and institutional affiliations.

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。

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。

⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。

天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。

Molecular Crystals: Full molecules are bonded to one another within an organized fashion. A good example is often a sugar crystal, which contains sucrose molecules.

This Review website chronicles above twenty years of exploration into developing a genetic code for crystal engineering. Instead of directing biological procedures, this code uses synthetic sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which nearly just about every facet of the resultant constructions is usually systematically managed. Inside this conceptual framework, the structural and functional developments are described in an effort to determine the present degree of sophistication and also to forecast upcoming directions on the System.
