Through the comparative analysis , the familiar red gems present the ohvious difference in colorimetry: With the approximate hue angle , the order of red gems lightness , from hig to small , are tourmaline , spinel , garnet and ruhy; With the approximate hue angle , the order of red gems color a * and chroma C * from hig to small , are tourmaline , ruhy , spinel , and garnet , the order of red gems color h * , from hig to small , are garnet , spinel , ruhy and tourmaline. Therefore , it can make a preliminary comparative analysis on the familiar red gems of colorimetry hy using the fi
