Black spinel is a stone with a brilliance said to rival black diamonds. Diamond cuts and other precise cut processing with sharp angles give it a sparkling and strong shine, highlighting its beauty. *Notes before purchase* ※We try to photograph the product in colors as close to the actual item as possible, but the color may appear different depending on your monitor or smartphone. ※As it is a natural stone, the color and shape vary.
