both amethyst and citrine coloring.

ametrine in interesting pendants during both February
is quartz that displays both citrine and amethyst colors
in one crystal. Ametrine occurs naturally and is mined
in Bolivia. It is also artificially produced by heat-treating
a portion of an amethyst. Ametrine makes an interesting
fashion statement in pendants and earrings by displaying
two colors at one time. It is usually emerald cut so the
two colors show half and half on the stone; however, some
artistic cutters will play with cuts that show a mix of
color throughout. Ametrine, like amethyst and citrine,
is appropriate for daily wear but steam cleaning and abrupt
temperature changes should be avoided.
