景观水晶，就是包裹体组成各种造型特异的水晶，有的似山水，有的似人物，有些像文字，有些像动物，植物，器物等等。

. These four structures comprise the majority of the binary crystals with equivalent numbers of cations and anions.
, has exactly the same construction, but there are two possibilities for selecting the holes the atoms will occupy. The third layer may be positioned in excess of the atoms of the main layer, creating an alternate layer sequence A
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
市场上有很多人把熔炼水晶也叫做合成水晶，那是不准确的，一般都是以水晶废料为原料在高温高压下熔炼出来的，而不是结晶成的，不具备水晶的晶体特性，所以不能把熔炼水晶与合成水晶混为一谈；但是熔炼水晶耐高温，用优质二氧化硅熔炼成的熔炼水晶可以做成实用产品比如水晶杯、烤盘、茶具等，实际上一代伟人毛泽东主席的水晶棺就是选用东海优质水晶熔炼而成的。
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：
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。
There are two these types of probable periodic arrangements. In Every single, the main layer has the atoms packed into a aircraft-triangular lattice in which each atom has six instant neighbours. Determine 2 demonstrates this arrangement for that atoms labeled A
Orthorhombic: These are definitely rhombic prisms and dipyramids that resemble tetragons but with out square cross-sections.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
One more form of crystalline carbon is predicated with a molecule with 60 carbon atoms known as buckminsterfullerene (C60). The molecular condition is spherical. Each and read more every carbon is bonded to three neighbours, as in graphite, as well as the spherical condition is obtained by a combination of 12 rings with 5 sides and twenty rings with 6 sides. Related buildings had been first visualized with the American architect R. Buckminster Fuller for geodesic domes.
