This is a set of 20 handmade natural amethyst materials. The size of each piece is approximately 2.5cm to 3cm, including the jump ring. Amethyst is a type of quartz, also known as "purple crystal," and is considered the highest-ranking stone among quartz varieties. It is quartz colored purple by iron, and those with deep, uniform colors, due to less color unevenness, 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 each natural stone.
