What does the term "stabilized turquoise" refer to?

The term "stabilized turquoise" specifically refers to turquoise that has been treated with polymers to enhance its durability and improve its appearance. This process involves impregnating the porous turquoise with a polymer resin, which fills in the microscopic spaces and helps prevent breakage and reduces the likelihood of discoloration.

This treatment allows for a more stable stone that can withstand everyday wear, making it more suitable for jewelry applications where durability is essential. By increasing the toughness of the turquoise, stabilization also enhances its marketability, as untreated turquoise can be more fragile and susceptible to damage over time.

The other options describe different methods of enhancing or altering turquoise, but they do not specifically refer to the stabilization process involving polymer impregnation.
