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。
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
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。
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
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�?”。

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：
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
The fundamental models of solids are possibly atoms or atoms that have blended into molecules. The electrons of an atom transfer in orbits that form a shell construction round the nucleus. The shells are filled in a systematic order, with Just about every shell accommodating only a little number of electrons. Different atoms have diverse quantities of electrons, that are distributed in a very attribute Digital composition of filled and partially loaded shells.
The sodium chloride crystal lattice is characterized by the website close packing on the positive sodium ions and destructive chloride ions. Each individual sodium ion is surrounded by 6 chloride ions, and each chloride ion is surrounded by 6 sodium ions, making a hugely secure and symmetrical framework.

Binary crystals are located in numerous buildings. Some pairs of elements form multiple composition. At home temperature, cadmium sulfide may crystallize both in the zinc blende or wurtzite composition. Alumina also has two probable buildings at place temperature, α-alumina (corundum) and β-alumina. Other binary crystals show diverse structures at distinct temperatures. Among the most sophisticated crystals are These of silicon dioxide (SiO2), that has seven distinctive buildings at a variety of temperatures and pressures; the most typical of these constructions is quartz.
