There are three ways that Zincite, a Zinc Oxide mineral, is formed.  The first occurs in nature, the second during a smelting process, and the third is lab-created.  Since it is made from metamorphosed orebodies or as a product of volcanism, naturally occurring Zincite crystals are rare and tend to be very small.  In its natural form, it often occurs with Calcite, Willemite, and Franklinite.
 
In the United States, the world’s best crystals come from the Buckwheat Mine located in Franklin, New Jersey.  Other quality specimens come from Sterling Hill near Ogdensburg, New Jersey.  Some Zincite has also been found in the Tonopah-Belmont Mine in Arizona.  Only a few with the deep red color, caused by trace amounts of iron and manganese, have been cut.  One is on display at the Smithsonian Museum of Natural History in Washington.  It weighs 20.06 ct.  The others are in the American Museum of Natural History in New York.
 
The smelter version came mainly from foundries in Poland but also occurred in smelters located in Italy and the United States.  The crystals that grew there were an accidental by-product of the gas handling system used by the Zinc smelting process.  The crystals formed over the years in the cavities of the smokestacks.  Pure Zinc is white.  The colors of these crystals and clusters are red, orange, yellow, brown, white, green, and bluish.  Pieces may be composed of one color or any combination of colors.  In the 1990s, EPA regulations were put into place to correct air pollution problems at the smelters.  These changes have resulted in no further production of Zincite from the smelting process.
 
People have tried to reproduce the gas handling system which resulted in the production of Zincite, but have had little success.  I did find information stating that lab-produced Zincites exist, but there was no information on what process was used to create them.
 
Some Zincite fluoresces a strong electric green under both long-wave and short-wave ultraviolet light.  The synthetic smelter versions have a wet glassy look rather than the crystalline appearance of natural Zincite.  Both have the same chemical composition and are a 4 on the Mohs scale. 
 
Natural deposits of Zincite are found in Australia, Namibia, Poland, Spain, Tasmania, and the United States (Arizona, and New Jersey).

Metaphysical Properties:  Zincite has a top-down energy feel to it.  Since it enhances creativity and helps one to manifest or transform rapidly, this makes sense because what one imagines in the higher chakras is then brought down to the lower chakras to manifest those ideas into reality.  It clears energy blocks, brings an excitement for life, and helps one to adjust to any changes occurring in their life.  Zincite is also helpful for someone who has suffered a shock or trauma by giving them the courage to deal with the situation and to release any depression or painful memories associated with it.  It energizes all of the chakras and helps a person open to the higher frequencies of the third eye and crown chakras while firmly anchoring the light body in the physical realm.  To manifest a monetary increase, combine it with Golden Labradorite or Heliodor.
