Matrix is the term used to describe the contrasting material in a parent rock – usually turquoise.
Matrix can be thick channels or delicate fine lines like a spiderweb.
It is usually made of iron pyrite and can look like fleks, spots or distinct veins.
Some people like stones WITHOUT matrix – they are called “clear stones”.
Other people are drawn to the variations in the shapes and colors of turquoise with matrix.
Matrix can add texture to the stone as well as a bit of glimmer in some cases.
The most common matrix colors seen in turquoise are black, brown and honey.
When turquoise is cut so that there is more Mother Rock than Turquoise, it is called Boulder Turquoise. So in this case the “veins” are turquoise !
So many beautiful stones to enjoy !
