Cacoxenite is a mineral that is an inclusion in quartz. It appears as gold or brown acicular needles.
Most experts now claim that the gold inclusions in the Amethyst are not Cacoxenite inclusions, but rather Geothite. It is said that Cacoxenite can never form in Amethyst as there is no phosphorus in the environments in which they crystallized.
However some of these cabochons also do include Cacoxenite, Clear Quartz, Smoky Quartz, Rutile and Lepidocrocite.
In any event these Amethyst gemstone cabochons are very unique and beautiful!
