Ametrine is the name used for quartz in which both amethyst and citrine occur together.
The stone samples originated from the Yuruty mine that is located in the geologic unit (Murcielagos limestones) in South America, Santa Cruz Bolivia. In Yuruty mine the stones present an interesting new aspect to the bicolored quartz. In addition to the typical amethyst and citrine sectors (along the major and minor rhombohedral forms) shows a pattern of two distinct layer of smoky quartz. These layers are oriented parallel to the minor rhombohedral form z within the citrine sector. In the slightly polished crystals, the smoky layers were observed just bellow the surface. In this area, the color of both amethyst and citrine is rather pale. The two (broken) fragments that did not show smoky quartz layers were presumably derived from the central portion of crystal; they did display more intense amethyst / citrine coloration. The growth conditions of this unusual ametrine evidently facilitated the enhanced accommodation of aluminium impurities in the z sectors. Natural irradiation of these aluminium-rich zones would give rise to the smoky quartz color layers.
