摘　　要：近期,在客户送检的一批和田玉饰品中发现一件拼合处理迪开石,外观与和田玉极为相似。经宝石显微镜、红外光谱仪、X荧光能谱仪测试,结果显示,白色部位摩氏硬度约为3,在显微镜下白色部位可见絮状物,具有"萝卜纹"结构;褐红色部位可见细小气泡群。红外光谱测试白色部位主要成分为迪开石,褐红色部位为人造树脂;X荧光能谱显示白色部位主要含有元素与寿山石的成分相符。根据国家标准GB/T16552-2010《珠宝玉石名称》,该样品为拼合处理迪开石。Recently,a spliced dickite has been found in a batch of Hetian jade jewelry sent for test by a client.The appearance of it is very similar to that of Hetian jade.The test results of Gem Microscope,infrared spectromete and XRF multi-element spectrometer show that Mohs hardness of the white protion is about 3 and floccule can be observed in the white portion with a “radish vein”structure under microscope.In the maroon protion of it,tiny bubbles can be seen.The main component of the white portion of the stone is dickite under the infrared spectromete test and the maroon protion is artificial resin.XRF multi-element spectrometer test indicates that the main elements contained in the white portion coincide with those of agalmatolite.According to the national standard GB/T1 6552-2010 《Gem Nomenclature》,this sample is a spliced dickite.
