通过 LA-ICP-MS 测量的 Ba 和 Pb 浓度，可以高度可靠地区分来自地中海的珍贵珊瑚 Corallium rubrum 和来自太平洋的 C. japonicum。与 C. japonicum 相比，C. rubrum 珊瑚含有更高的 Ba 和 Pb（分别>6 和 >0.2 ppm）。这种化学指纹识别技术是作者小组在之前的研究中开发的，并在三个已知来源的抛光红珊瑚凸圆面上进行了成功的测试。这种破坏性最小、相对便宜且易于实施的方法可以通过区分 CITES 列出的 C. japonicum 和非 CITES 列出的 C. rubrum 珍贵珊瑚来帮助执行贸易法规。 (C) 2021 Gem-A（英国宝石协会）
Concentrations of Ba and Pb measured by LA-ICP-MS make it possible to distinguish the precious corals Corallium rubrum from the Mediterranean Sea and C. japonicum from the Pacific Ocean with a high degree of confidence. Compared to C. japonicum, C. rubrum coral contains higher Ba and Pb (>6 and >0.2 ppm, respectively). This chemical fingerprinting technique was developed by the authors' group during prior research and is successfully tested here on three polished red coral cabochons of known origin. This minimally destructive, relatively inexpensive and easy-to-implement method can help enforce trade regulations by distinguishing CITES-listed C. japonicum from non-CITES-listed C. rubrum precious corals.
