Part of speech: noun
Definition: The term 'star effect' in the jewelry industry describes the phenomenon of asterism, where a star-like pattern appears within certain gemstones when they are cut in a cabochon shape and exposed to direct light. This effect is the result of light reflecting off of needle-like inclusions within the stone, arranged in a way that creates the appearance of a four, six, or even twelve-point star. Commonly found in stones like sapphire, ruby, and garnet, the star effect enhances the gem's aesthetic appeal and value. The intricacy of this natural feature makes each star-bearing gemstone unique, offering a mesmerizing visual experience that is highly prized by collectors and jewelry enthusiasts alike. This distinctive characteristic not only signifies the rarity and beauty of the gem but also contributes to the allure of the jewelry pieces in which these stones are set.
