珊瑚
珊瑚是一种生活在海洋里体态玲珑,色彩艳丽的腔肠动物,称为珊瑚虫,珊瑚虫能分泌出红、白色等石灰质骨骼,并群集在一起形成的骨骼化石,多数呈树枝状,即人们所说的珊瑚。

珊瑚的分类
深海贵重宝石级红珊瑚主要指:阿卡(亚洲珊瑚),沙丁(地中海珊瑚),MoMo(亚洲珊瑚), 同等质量级别的三种红珊瑚,价格排列顺序为阿卡>沙丁>MoMo

  1. AKA阿卡珊瑚
    AKA阿卡珊瑚,枝面光滑细腻无纹, 一般有白芯。阿卡是日文赤(红)的音译 ,其活枝倒枝特征是玻璃光感微透明,结构紧密,纹路细腻,一般正面不容易看到生长纹路,有明显白芯,为亚洲珊瑚共有特征,白色生长点。阿卡珊瑚植株不算大,一般常见原料一株为3-0.8公斤,一株2公斤以上就属大型。
  2. 沙丁珊瑚
    沙丁没有明显的白芯,多数沙丁用来做串珠,和直管的。比阿卡的美观,但是没有阿卡密度好。沙丁的原料产区在地中海沿岸,以意大利为聚集地,沙丁的纹路还是比较清晰的,沙丁的颜色比较单一都是红的,没有亚洲珊瑚的白色中心点,但是有深浅之分,密度变化也比较大,有些密度低有些密度高。颜色越深的密度越高的,其价值越高,价格也越高。沙丁珊瑚的植株比较细小,直径超过10mm的就算大型的了,所以市面上珠子直径超过10mm,密度颜色都好的沙丁,其价值也很高。
  3. MOMO珊瑚
    MOMO是另一种深海珊瑚,植株比较粗大。一般在2-3公斤居多,常有高25-50公分的植株。现在常见的为倒枝托体或死枝,颜色普遍偏橙,偏桃色。MOMO是日语音译,MOMO珊瑚没有阿卡那么脆,用于雕刻的比较多,一般生长纹路比较清晰,没有阿卡的光感强。阿卡和MOMO的共同特点就是都有白芯, 是亚洲珊瑚的共同特点。

珊瑚的特性
珊瑚是宝石中比较少有的东西方文化有共识的宝石,普遍都认为珊瑚寓意吉祥、能带来好运。从古罗马开始,西方人就认为珊瑚具有防止灾祸、给人智慧、止血和驱热的功能。印度和中国西藏的佛教徒视红色珊瑚是如来佛的化身,他们把珊瑚作为祭佛的吉祥物,多用来做佛珠,或用于装饰神像,是极受珍视的首饰宝石品种。
中医认为珊瑚有较强的药用功效,可以去翳明目、安神镇惊,治目生翳障,惊痫,吐衄。 据说小朋友佩戴的话,有保护骨骼成长的效果,红色或粉红色珊瑚尤其对血液方面的疾病有探测的功能, 脏病及神经系统疾病离患者也很适合佩带。珊瑚对皮肤, 指甲,头发等生长都有帮助。
随着珠宝收藏业多元化发展,珊瑚受到市场人士的追捧,由于红珊瑚采掘数量越来越少,珊瑚饰品摆件具有较高的升值潜力。

珊瑚的保养
琥珀是天然有机宝石,硬度和燃点较低,因此避免摔砸磕碰和暴露在高温下,珊瑚的日常佩戴和保养请参考以下建议
1珊瑚的化学成份是CaCO3,化学性质不稳定,酸性物质会侵蚀珊瑚饰品,避免接触醋酸,汗液呈弱酸性,因此夏季佩戴后应立即擦干妥善保存。
2珊瑚不宜多接触化妆品、香水、酒精、食盐、油污和醋等。珊瑚的结构不致密、有孔隙,易弄脏,清洗时用中性肥皂水。
3远离高温和漂白性的物质,珊瑚的颜色对其价值影响甚重,高温和漂白剂都会破坏有机色素引起退色。
4、 珊瑚饰品不能长时间在水中浸泡,使用纯净水或温开水清洗珊瑚饰品,清洁后立即用质地细腻的软布擦干。不要在洗澡、游泳、桑拿、温泉时佩戴。
5、清洁后的珊瑚饰品表面可涂抹薄薄一层透明的中性油脂来隔离空气和有害物质,但要注意只能使用无香精、无色素的油脂,如矿物质油、婴儿润肤油。
6、珊瑚硬度不高、脆性较大,除了需要单独存放外,在佩戴中也一定不要发生跌落和碰撞。


钻石及彩色宝石
