Ametrine Description
Transparent, bicolored quartz with the colors of both amethyst and citrine in the same gem is call ametrine or amethyst-citrine. The contrasting colours give it an intriguing appearance.
Ametrine is often cut as a rectangular step cut because that style nicely displays the bicolour effect. Cutters try to emphasise both colors equally. Cutters sometimes fashion kametrines as mixed cuts or brilliant cuts and use internal reflections to mingle the amethyst and citrine colors.
Fine ametrine shows medium dark to moderately strong orange, and vivid to strong purple or violets purple. Larger gems, tend to show the most intensely saturated hues.
