摘　　要：通过对市场上两只手镯样品进行常规的宝石学测试、红外吸收光谱测试,发现这两只手镯均为和田玉,且都经过了浸无色油的优化方法。通过对其中一只手镯N-1浸无色油实验,对比实验前后的手镯N-1的外观差异,结果显示,和田玉手镯N-1是经过了浸无色油的优化方法,油析出之后,手镯N-1里原本就存在的白色棉絮显露出来。将手镯N-1在一定的温度条件下浸无色油,油充填了矿物之间的间隙,即而看不到手镯里的白色棉絮。浸无色油能很有效地改善和田玉手镯的外观,使和田玉手镯看起来更油润更漂亮,但效果不是很稳定,需要反复浸无色油。Through the routine gemmology test and infrared absorption spectrum test of two bracelets on the market,it is shown that these two bracelets are nephrite,and both of them have been optimized by being soaked in colorless oil.One of the bracelets N-1 is soaked in colorless oil,and the appearance difference of the bracelet N-1 are compared before and after the experiment.The experimental result shows that nephrite bracelet N-1 is optimized by being soaked in colorless oil.After the oil is separated out,the white cotton wool originally existed in the bracelet N-1 is exposed.To soak the bracelet N-1 in colorless oil at a certain temperature,the oil fills the gap between minerals,so the white cotton wool can not be seen in the bracelet.Soaking colorless oil can effectively improve the appearance of nephrite bracelet,making it look more oily and beautiful.But the effect is not very stable,and it needs to be soaked repeatedly in colorless oil.
