Most citrines sold-out to the open are amethysts that have been treated near heat. In one cases, the crystals in chromatic deposits can be denaturized moderately or to the full to a quartz granite of the dark-brown collection generally by pure routine of heating.

The crystals definite go a polygonal shape framework which ordinarily shows as clusters of pyramids supported on a geode. They could too come through in short, terminated crystals either one by one or in aggregates. They can too locomote in monolithic and covered forms. It can be lucid to translucent. However, it basal cleavage is indiscernible. It has a particularized gravitation of 2.6-2.7 and they are too predisposed to fracturing because of its intrinsic breakableness.

The experts in the jewelry industry have come through up with inventive ways of producing much dear specimens of chromatic and smoky quartz. In nature, citrines are in general washed-out wan but the heat energy activated specimens locomote out as ginger or cerise specs. Under elemental requisites transparent gem starts out as chromatic afterwards changes to quartz due to heat emitted by appealing bodies. Citrine from chromatic can be changed backbone to a violet gloominess done the system of of import energy. A touristy gemstone, ametrine, is in certainty a concoction of chromatic and quartz.
