Quantitative characterization appreciation of golden citrine golden by the irradiation of [FeO4]4−
With the help of irradiation, [FeO4]4− was excited by one electron from ferric electronic shell, it absorbed the visible light of 550 nm, and then made crystal appears golden color which named citrine. 27 pieces citrine was confirmed as natural from 32 pieces golden citrine by IR technology, their c...

| description | With the help of irradiation, [FeO4]4− was excited by one electron from ferric electronic shell, it absorbed the visible light of 550 nm, and then made crystal appears golden color which named citrine. 27 pieces citrine was confirmed as natural from 32 pieces golden citrine by IR technology, their color parameters were calculated by the colorimeter tests, then how could hue, lightness and chroma contribute to visual color were analyzed too. It reveals that chroma of natural citrines are negatively correlated with hue and lightness, by the control of hue angle on the impact of the chroma, the co-effect of hue and lightness of natural citrine produce moderate influence on chroma. Without the consideration of chroma influence on lightness, lightness and hue angle are high correlated (r = 0.924), it is tested the high linear correlation of citrine lightness and hue; while with the consideration of chroma influence on lightness, lightness and hue angle also high correlated (r = 0.897), and the high linear correlation of citrine lightness and hue is confirmed. It draws conclusion that in the limit the citrine golden, lightness should be regarded as the first factor when citrine quality evaluation was taken, with the most intuitive representative and most consistent with the expression of perception effect, then the effect of hue and chroma was considered furthermore.
