GEMOLOGY
The term “spider webbing” is used to describe turquoise with thin lines of matrix running throughout them, much like a spider’s web. In some parts of the world, turquoise stones with matrix are considered imperfect and clear turquoise stones are most desired but in the US, spiderweb turquoise has much more appeal and value. When other materials appear within turquoise, those materials which often look like veins, are referred to as matrix or part of the “mother rock”.
