Natural turquoise is a hydrous aggregate of copper and aluminum. Turquoise gets its color from the amount of either copper or iron present. Vivid blue turquoise is a result of high copper content and the softer green tones result from iron. Turquoise stones have varying degrees of matrix. True turquoise has an opaque, waxy luster that may or may not include matrix, depending on the type. Turquoise gems can be found across the world, including the United States, Mexico, Iran, northern Chile and China, though many turquoise mines have closed.
Matrix is the vein-like inclusions that run through turquoise. Turquoise matrix is basically some of the host stone that housed the turquoise as it formed. Turquoise gemstone forms as a result of water (containing certain minerals and aluminum) leaking through a rock, then being subjected to heat and pressure. The turquoise stone forms as clumps or nuggets in cracks of porous rock, sometimes alongside other gemstones such as chrysocolla. As far as matrix value, that is up to personal preference. A lot of the Southwest states in America and the Far East consider matrix to be beautiful. Black matrix is a result of iron pyrite (iron sulfide). This is typically the most favored matrix color. Yellow matrix is the result of rhyolite and brown matrix is the result of different types of iron oxide.
