对这类水晶晶簇观赏石的欣赏与评价，主要是强调晶体的完整、品种的名贵（如紫水晶、烟晶、发晶等）、造型奇特、含有名贵晶体（如辰砂、辉锑矿等）伴生等。晶簇产于矿床晶洞中，长相完美的并不多见，要完整无损地采集下来，又比较困难，故而采集起来代价较大，精品晶簇价值也就昂贵了。
Bismuth (Bi) appears to be a steel, but the quantity of electrons obtainable for electrical conduction is similar to that of semiconductors. The truth is, bismuth known as a semimetal. Molecular solids are frequently crystals shaped from molecules or polymers. They can be insulating, semiconducting, or metallic, with regards to the kind of molecules in the crystal. New molecules are continually becoming synthesized, and a lot of are made into crystals. The volume of diverse crystals is enormous.
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
Tetragonal: These crystals sort prisms and double pyramids. The framework is like a cubic crystal, except one particular axis is for a longer time than one other.
2She was donning a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》
发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
Ionic Crystals: Electrostatic forces sort ionic bonds. A basic illustration is usually a halite or salt crystal.
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：

. The next layer is shaded during the determine. It's exactly the same airplane-triangular structure; the atoms sit while in the holes fashioned by the main layer. The primary layer has two equivalent sets of holes, but the atoms of the 2nd layer can occupy just one set. The third layer, labeled C
The sodium chloride crystal lattice is characterised via the shut packing with the favourable sodium ions and detrimental chloride ions. Each individual sodium ion is surrounded by 6 chloride ions, and every chloride ion is surrounded by six sodium ions, developing a highly stable and symmetrical construction.
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
Binary crystals are found in a lot of buildings. Some pairs of factors variety more than one construction. At home temperature, cadmium sulfide may crystallize both inside the zinc blende or wurtzite framework. Alumina also has two probable structures at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit diverse structures at unique temperatures. Amongst the most complicated crystals are These of silicon dioxide (SiO2), which has seven unique structures at many temperatures and pressures; the most common of such structures is quartz.
