Which type of turquoise is known for having web-like matrix patterns?

Spiderweb turquoise is characterized by its distinct web-like matrix patterns that resemble the intricacies of a spider's web. This unique formation is typically caused by the presence of matrix minerals that become intertwined with the turquoise, adding a decorative element to the stone. The distinct appearance of spiderweb turquoise makes it particularly sought after for jewelry and decorative pieces.

Stabilized turquoise refers to treatments applied to improve the stone's durability and enhance its color, but it does not specifically denote the web-like patterns. Natural turquoise can come in various forms but does not inherently denote the presence of matrix patterns; it simply indicates that the stone has not been artificially altered. Dyed turquoise involves color enhancement processes to achieve desired hues, and like stabilized turquoise, it does not refer to the matrix designs found in spiderweb turquoise.

Therefore, spiderweb turquoise stands out for its visually striking web-like patterns, making it the correct choice in this context.
