How & Where is it Formed?

TurquoiseIf it's not blue, what's it to you?

Physical Properties

The mineral turquoise is formed when rainfall infiltrates downward through soil & rock, dissolving small amounts of copper. When that water has been evaporated, the copper unites with the aluminum & phosphorus to deposit tiny amounts of turquoise on the walls of the subsurace fractures. The turquoise can also replace the rock that is in contact with the waters. If the replacement is complete, a solid mass of turquoise will be formed. Turquoise is mostly found in Northern Iran, Southwest of the United States, Pakistan, Mexico, Israel, & China.
