摘要:
选用市场上常见的紫红色、橙色、粉色、绿色、黑色处理珍珠,粉橙色、金黄色铍扩散蓝宝石,充胶翡翠作为研究对象,通过设计耐久性实验,对样品颜色的稳定性进行了研究。结果显示,充胶翡翠和铍扩散蓝宝石在日晒、盐雾及人工汗液中均表现出了良好的颜色稳定性;处理珍珠在盐雾环境中表现出了较好的稳定性,在模拟日光照射试验中褪色明显,而经过人工汗液腐蚀,其颜色表现出了较差的稳定性。对样品颜色稳定性的研究,可以为优化处理宝石的市场准入提供一定的依据。
Abstract:
We have chosen some common materials like purple, orange, pink, green, black treated pearls, pink orange, golden yellow sapphires with beryllium diffusion treatment, and filled jadeites as samples, and have made experiments to analyze their colour durability. The results show that filled jadeites and beryllium diffusion treatment sapphires show good durability after the exposure to sunshine, the salt spray environment and artificial sweat. The treated pearls show good durability in the salt spray environment, fade clearly under the exposure to sunshine, and suffer colour damage for daily contact with sweat. The study on the colour durability of the samples can provide some bases and reference for the market access of enhanced and treated gemstones.
