Luster refers to the way light interacts with the surface of a stone or metal, indicating its quality and finish.

Part of speech: noun
Definition: In jewelry, luster is a critical attribute that describes the quality of light reflected from the surface of gemstones or metals. High-quality gems and polished metals display a brilliant, mirror-like luster, which greatly enhances their beauty and perceived value. The luster of a gemstone is determined by its intrinsic properties and the quality of its cut and polish. For metals, such as gold, silver, and platinum, luster indicates the level of polish and fineness, contributing to the overall aesthetic appeal of the jewelry piece. Different types of luster, such as metallic, glassy, or silky, can significantly affect the allure and desirability of the piece, making luster an essential consideration in jewelry design and selection.
