Ametrine is a variety of quartz that
contains both amethyst and citrine sectors in the same crystal.
Sometimes amethyst and citrine colors are found in the same crystal
of quartz. These bicolor yellow and purple quartz gemstones are
called ametrine.
Ametrine can be cut to blend the two colors so that the resulting
stone is a mix of yellow, purple, and peach tones throughout the
stone. Ametrine is a durable gemstone that is suited for a variety
of jewelry uses. The hardness of ametrine is 7 with a vitreous
luster.
The Anahi mine in Bolivia is the natural ametrine source. At this
location, both amethyst and citrine are thought to have been
crystallizing simultaneously during formation. Ametrine is said to
have all the metaphysical properties of both amethyst and citrine
combined, as well its own unique properties; aids in meditation,
relieves tension, disperses negativity and helps to eliminate
prejudice. Ametrine is readily recognized by its colors, hardness,
glassy luster, conchoidal fracture and lack of cleavage.
