摘要

ket，具有不同于天然菱锰矿的宝石学性质、化学成分和结构特征。在这项研究中，通过标准宝石学测试、扫描电子显微镜、能量色散光谱、X射线衍射、FTIR和拉曼显微光谱检查了四个样品——两个仿制品和两个菱锰矿。检验表明，仿制品由挤压三水铝石和方解石粉末组成，具有颗粒结构，通过标准的宝石学测试很容易识别。

Pressed Gibbsite and Calcite as a Rhodochrosite Imitation

ket, with gemological properties, chemical composition, and structural characteristics that are different from natural rhodochrosite. In this investigation, four samples— two imitations and two rhodochrosites—were examined by standard gemological testing, scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction, FTIR, and Raman microspectroscopy. Examination revealed that the imitations are composed of pressed gibbsite and calcite powder with a granular structure, which are easy to identify through standard gemological testing.
