天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
Fig. seven: A template-directed approach can Handle the placement of setting up blocks on a floor in the formation of advanced constructions.
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
结晶�?When sea water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：
Hexagonal �?Characterized by 4 axes, a few of which might be equivalent in size and intersect at 120 levels, which has a fourth axis perpendicular to the opposite three.
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：
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。
. The second layer is shaded within the figure. It's the identical airplane-triangular framework; the atoms sit during the holes formed by the first click here layer. The main layer has two equivalent sets of holes, however the atoms of the next layer can occupy only one established. The 3rd layer, labeled C
Orthorhombic: These are definitely rhombic prisms and dipyramids that resemble tetragons but without having sq. cross-sections.
This Evaluation chronicles more than twenty years of research into making a genetic code for crystal engineering. As opposed to directing Organic procedures, this code makes use of synthetic kinds of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which almost each individual facet of the resultant buildings is often systematically controlled. Within just this conceptual framework, the structural and useful innovations are explained in an effort to define the current amount of sophistication and also to predict long run directions of the platform.
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
