天然水晶的美丽魅力（图）
什么是水晶？
水晶是狭义宝石中的一类，是一种很古老的宝石。其化学成分为二氧化硅。这是石英族矿物中透明如水的结晶体（虽结晶而不透明者，只能称石英晶体）。若因含有杂质而形成紫色、茶色或黑色时，则分别称其为紫晶、茶晶和墨晶；内部含有针状或纤维状矿物包裹体的特殊品种叫“发晶”。水晶晶面呈玻璃光泽，其贝壳状断口则油脂光泽；硬度为7，比重2.66，并具有压申性和光学性质。水晶用途很广，在珠宝中主要用作手链和项链珠，也做一些小挂件和摆件，水晶主要产于巴西、乌拉圭，中国主要产地是海南省的羊角岭和江苏省的东海。
天然水晶清澈透明，常含星点状、云雾状或絮状展布的气液包体，并常可见到微裂纹。人工合成水晶毫无裂纹，却常有小气泡。此外，用手掂量可感到合成水晶比重大于天然水晶。和玻璃比，水晶色白而多明亮耀眼，玻璃白中微泛青色、黄色且感明亮不足；水晶硬度为7，玻璃为5.5，可用水晶划玻璃，天然水晶常含有绵纹等不均匀，不完美现象，而玻璃因人工焙炼，常均一而无绵纹，并有微小气泡，用舌舐水晶有凉感，玻璃有温感。
======================================================
明代著名医学家李时珍在《本草纲目》中说，水晶“辛寒无毒”，主治“惊悸心热”、能“安心明目、去赤眼、熨热肿”等。还可治疗“肺痈吐脓、咳逆上气”、“益毛发、悦颜色”等，具有极其重要的医疗功能。
水晶的理疗和保健作用按照现代科学观点，可以从以下几个方面来理解:
一、天然水晶具有特殊的“压电效应”。无缺陷的水晶单晶经加工成饰品佩戴人体后，与人体摩擦可以产生微弱的电磁场，这种电磁场具有稳定情绪，促使人体能量集中，减轻病人痛苦和紧张，加快痊愈速度等功能。如美国研究中心所推崇的“水晶疗法”，就是将水晶按压在病人伤患处起辅助治疗作用的。
二、从水晶的光学特性看，水晶居三方晶系的一轴晶正光性结晶体，有三个方向的光轴，当按方位精工切削琢磨后，光轴方向往往会产生一定聚光、放光功能，当其刺激到人体某一穴位时，可以产生一定的理疗作用。国外报道的用水晶治疗少儿骨折、乳腺癌等均基千这一道理。
三、从生物地球化学观点来看，水晶同其它宝石一样，形成于特殊的地质构造环境，含有部分对人体有益的微量元素，如铁、铜、锰、钦、锌、镍、钻、硒等，烟水晶由于形成时受到地下放射性照射而保留有少量放射性元素(含量极微，不会对人体有害，反而类似放射疗法)，这些微量元素通过与人体的经常摩擦而会沿毛细孔汗腺等浸入到人体内而促进体内微量元素平衡，使身体备部分更加协调。

白水晶：有聚焦、集中、扩大记忆的功能，是所有能量的综合体，称晶王。可镇宅、辟邪、挡煞，净化全身，去除病气，趋吉开运。
