~ Meaning of Stone:
Turquoise is a Hydrated Copper Aluminum Phosphate that belongs to the phosphate class of minerals. Most specimens are cryptocrystalline, meaning that the crystals could only be seen by a microscope.
The color is blue but also occurs as, blue-green, green-blue, brown-green and sky blue, they have a dull to waxy luster. The matrix is the most obvious inclusion in Turquoise. It is the left over remains from the host rock in which the turquoise grew. The webbing can be black, brown, yellow or a host of other colors. Over long periods of time this matrix erodes away. When this happens the matrix and the Turquoise are at different heights and this creates a type of over growth.
