Ametrine, also known as trystine, is a bicolor gemstone occurring when amethyst and citrine colors are found in the same crystal of
quartz. The gemstone ametrine thus contains yellow citrine and purple amethyst. It has a hardness of 7 on Mohs Scale.
The Anahi Mine in Bolivia is the major producer of ametrine, and it first became famous when a Spanish conquistador received it as a
dowry when he married a princess from the Ayoreos tribe in the seventeenth century. The conquistador's gifts to the Spanish queen first introduced the
gemstone to Europe.
Ametrine, most typically faceted in a rectangular shape with a half and half pairing of amethyst and citrine, is a very durable gemstone
suited for a variety of jewelry uses. Most sizes and shapes are available but the color contrast is most pronounced in sizes over seven carats. Many
artists like to play with the colors to create very interesting effects.
Ametrine is believed to have metaphysical properties that aid in meditation, relieve tension, disperse negativity, and help to eliminate
prejudice as well as the metaphysical properties of both amethyst and citrine.
