The Mineral Crocoite

Crocoite is a lead chromate containing mineral that crystallizes in a crystal system that is monoclinic. Its composition is identical to a synthetic product named chrome yellow that is used as a paint pigment.

Chemical Formula  
Lead Chromate PbCrO4

Derivation of Name  
They discovered it first  at the  Berezovsk Mines in the Urals near Ekaterinburg during 1766. In 1832, F. S. Beudant named it crocoise after the  Greek word  (krokos), meaning saffron, drawing hint from its color. This name was first changed to crocoisite, and thereafter,  to crocoite.

Occurrence         
Big,  well formed crystals of crocoites can be found frequently, though badly terminated in many cases. Crystals in bright hyacinth-red color are translucent and possess a non-metallic luster. On getting exposed to UV light it loses some of its brightness.

Gemology  
This amazing stone can make you feel good about life. The crystal activates the base chakra and then connects and attaches you to the earth chakra, strongly connecting you with the energy of Mother Gaia. It works like a tonic to bring back energy and vitality and seems to add sparkle to life

Source               
Great quantities of rare specimens of Crocoite are discovered in Platt, Red Lead, Adelaide, West Comet and further in the Dundas Mines in Tasmania; we find them, normally in slim prisms, generally around 10-20 millimeters, and  occasionally around 200 millimeters or 4 inches. long. It has a bright sheen as well as color. The official mineral emblem of Tasmania is Crocoite. Other regions where crocoite is obtained in the fine crystallized form are in Brasil’s Congonhas do Campo adjacent to Ouro Preto, and in Mutare (Mashonaland),  adjacent to Menzies in Western Australia,besides which you can find them in  South Africa, Germany plus Brazil and Luzon in Philippines.

Mineralogy  
The deep orange red color of this attractive mineral captivates collectors. Initially, it was found in Russia and subsequently in parts of Europe, but scarcely and in tiny crystals. The discovery of its well formed, large and shiny crystals on the island of Tasmania in Australia brought the value of this mineral to an entirely new level. This discovery yielded exceptional crystals and aggregates, though material of outstanding quality continues to be mined from these mines which are now getting mined for producing specimen.

Color           
It comes in bright orange-red to yellowish-red color.

Density                               
5.97 g/cm3

Mohs hardness is                               
2.5–3
