文玩玉石的收藏正呈现出百花齐放的态势,在和田玉、翡翠价格被推至令人咂舌的高位后,南红玛瑙正成为投资者的新晋热宠。南红玛瑙摩氏硬度为6.5左右,与和田玉(Hm=6-6.5)、翡翠(Hm=6.5-7)相似,且韧性极好,颜色层次丰富,适合雕刻加工,佩戴保存也很简单。南红玛瑙自古就深受皇家贵族和佛家喜爱,佛家七宝中的赤珠指的就是南红玛瑙,“南红”一词是近年来才流行于珠宝收藏爱好者之间的,它是一种由细小三氧化二铁红色颗粒致色的红色玛 Wen jade jade collection is showing a flourishing trend in the Wada, Jadeite price pushed to a staggering high, the South onyx is becoming a hot new investor. South red onyx Mohs hardness of 6.5 or so, and Hetian jade (Hm = 6-6.5), Jade (Hm = 6.5-7) similar and excellent toughness, rich color levels, suitable for carving, wear is also very simple to save. South red agate ancient times loved by the royal aristocracy and the Buddha, the red beads in the Buddha’s Qibao refers to the South Red Agate, “South Red” is the word popular in recent years, between the jewelry collectors, It is a red mauve that is colored red with fine red ferric oxide particles
