I was collecting these. Some items are meant to be sets, so you can attach commercially available findings to make earrings or piercings. (Even with the same stone, there may be slight color variations due to the nature of natural stones.) They can also be used as pendants for necklaces or charms for other accessories as single items. Photos 2-4 show the contents of one natural stone set. Photos 12 and 13 show the size of one natural stone. The others are almost the same. *Due to the thickness, the natural stones and the included instruction manual will be packaged without the box. The box is not included. Although these are unused items, please understand that they are pre-owned due to home storage, and purchase accordingly.
