Metal alloy is a homogeneous mixture of a primary metal with other elements (metals or non-metals). This combination improves the base metal's physical properties, such as increasing strength, enhancing corrosion resistance, or reducing weight, making the material far more versatile than pure metals.
Patina is a thin surface layer that develops on metal jewelry due to age, use, or intentional chemical treatments. It often appears as a color change, like darkening or greenish tones, and is caused by oxidation. While sometimes considered a sign of wear, many jewelry makers intentionally apply patina to highlight details and create an antique finish.
