These are opaque, not transparent, and will glow under UV light.Please be aware that they are reflective, so take care when shining lasers at them. While these are radioactive from their uranium content, they do not emit enough radiation to be hazardous and are generally regarded as safe. These marbles have small surface imperfections.
