历代以来人们对广东肇庆端砚中的石眼十分关注，因为石眼是提高端砚的鉴赏品位和市场价值的重要因素之一。梅花坑砚石是端砚石中的一种，以梅花坑砚石的石眼作为样品，用显微激光拉曼光谱测试技术，研究和测定了石眼不同部位的矿物组成。实验结果表明，砚石和石眼中均有碳存在，只是砚石中石眼(含眼瞳、眼球、眼睑)附近的基体部位碳多以微晶石墨的物相形式存在，而在石眼的眼睑处的碳则以碳球形式存在；石眼的眼睑处颜色变黑，是由赤铁矿、石墨含量的增多以及黑色玻璃相的出现而引起的；相反，石眼眼球部位颜色变浅，是因为伊利石和石英是主成分、赤铁矿和石墨含量少以及没有绿泥石的存在而造成的。石眼的“瞳子”部位呈红褐色，是来源于金红石的颜色，不是行内长期以来认为的是由赤铁矿造成的。紫色端砚石品石眼的形成与火山作用密切相关，石眼是火山泥球在海湾或潮坪环境中沉积的粉砂质泥岩在后期浅变质作用条件下的变质残余。

Stone eye, a distinctive mark of Duanxi Inkstone, has attracted attention of inkstone lovers in the long history of inkstone utilization, this is simply because stone eye mark is one of the key factors that can effectively enhance the professional connoisseurship and increase the market value of inkstone. This study was focused on the stone eye on Duanxi inkstone from Meihuakeng pit in Zhaoqing. By using advanced Laser Raman spectroscopic technique fitted with microscope, the mineral composition at different parts of a stone eye mark was observed and tested. As indicated by our experimental results, carbon occurs in the groundmass around the stone eye mark of inkstone mainly in the form of graphite phase;Carbon also occurs at the eyelid of the stone eye mark is postulated to be resulted from increased contents of stone eye marks, but in the form of carbon microspheres. Dark color that happens at the eyelid consists of hematite and graphite and occurrence of black glass phase. In contrast, grey color that occurs at the eyeball of the stone eye mark is postulated to be resulted from major mineral constituents being illite and quartz, decreased contents of hematite and graphite and disappearance of chlorite. The maroon color at the pupil of the stone eye mark is resulted from rutile, rather than from the hematite, the latter being the long-held view of the academics. It is inferred that stone eye marks of purple Duanxi Inkstone are closely related to volcanism, as stone eye marks are resulted from light metamorphism of volcanic tuff-related dust that was deposited in the silty clay formed in the gulf or tidal flat sedimentary environment.
