杂质、裂纹越少越好。质地好的水晶制品,应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点,则属于次品。
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。
养殖晶:养殖晶是指,用天然水晶做种子,然后赋予天然水晶生长的高压条件,养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长,这样的水晶成分(分子式)与天然水晶是一摸一样的,唯一有差别的是,这样的水晶磁场作用没有天然水晶强。
. These 4 constructions comprise almost all of the binary crystals with equal figures of cations and anions.
Lattices could possibly have one lattice position per cell or more than one, yielding a complete of 14 Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array created by a list of discrete factors.
光泽:玻璃光泽。断口处为油脂光泽。光泽,指宝石表面对光线反射的一种光学性质。观察水晶的光泽,可用手握着它,以灯光或窗户投进来的光线看表面反射,透明水晶亮度与光泽强弱有关。
如果水晶内部杂质中有传说中人物的造型,如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
Crystals will often be considered as one thing of huge elegance, and they are commonly used with diamonds or other stones to help make items of jewelry. Virtually all crystals now are guy-produced in laboratories.
广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。
Solitary crystals of metals are comfortable and malleable, when polycrystalline metals are more durable and much better and tend to be more helpful industrially. Most polycrystalline supplies is usually produced into huge single crystals just after prolonged warmth treatment method. Before blacksmiths would heat a bit of steel to make it malleable: warmth would make some grains improve big by incorporating lesser ones. The smiths would bend the softened steel into shape and then pound it awhile; the pounding would make it polycrystalline all over again, growing its energy.
正常的水晶在生长时,多可以发现和柱形尖端棱线平行的生长纹(growth lines)。由于在地底、岩洞中的生长空间多狭窄,尤其在遇到地震时,或地壳变动时,甚至容易遭到其他矿石的挤压,常常会压迫产生不同的「晶面」。还有,当水晶还是在液态状的时候,常常也会包覆着其他的矿石、泥灰一起结晶成长,如金红石(稍后变成发晶)、火山泥灰(稍后变成幻影水晶)等等。所有的这些,都是「自然的一部分」,请不要视为「瑕疵」。
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。
