Amethyst pendant tops. This is a set of 30 pieces. The size of each piece, including the bail, is approximately 1.5cm to 2.5cm. Amethyst is a type of quartz, also known as "purple crystal," and is considered the highest-ranking stone among quartz varieties. It is a crystal colored purple by iron, and because of its color unevenness, those that appear deep and uniform in color are considered to be of higher quality. Natural stones are formed by nature. As they are not artificial, there is a possibility that cracks and inclusions (internal inclusions) may be included in the process of formation. This is not a defect, so please enjoy the individual expressions of the natural stones.
