Ink beryl, also known as morganite, as a rare species of beryl family, in the market is not much seen. Morganite is one of the most valuable gems in the beryl family. Because pink beryl came out relatively late, people’s recognition of it is still relatively low, and the research on its color genesis is very limited. This paper aims to explore its spectral characteristics and color formation mechanism. Six samples were collected for testing, including five natural pink beryl and one hydrothermal synthetic red beryl. The gemological characteristics of five natural samples were identified, and all samples were tested by large-scale instruments, including Fourier infrared spectrometer, laser Raman spectrometer, UV-VIS spectrophotometer, and X-ray fluorescence spectroscopic analysis. The experimental results show that the color of beryl synthesized by hydrothermal method is dark red and does not contain Cs , and the other five natural samples are pink and orange pink, all containing Cs . The substitution of Mn2 and Cs for Al3 is an important reason for the pink tone of pink beryl. The orange sample is yellowish brown because it contains Fe2 ions, and then mixed with pink to form orange pink. The color of red beryl synthesized by hydrothermal method is dark brown, which is due to the addition of a large amount of Fe2O3 and MnO2, and there is no Cs , so it does not show a pink tone. %K 粉红色绿柱石，颜色分析，X射线荧光光谱仪，光谱分析
