These are polished botryoidal chalcedony nodules. They generally have a blue-ish gray to white to gray color. They vary in size, shape, and color, and glow orange under shortwave UV light (365 nm). Choose the size you would like from the drop down menu.
As these are natural stones, please expect variation in polishing as these stones have areas that don’t polish as well due to their botryoidal nature.
