It is non magnetic and weighs 4 grams and its width and breath are around 2 cm and thickness is 1 cm A fun It is non magnetic and weighs 4 grams and its width and breath are around 2 cm and thickness is 1 cm This almost looks like a rock I have seen before. Im not sure what type of rock it is but it looks like it has quartz of some kind. Get a good powerful sonic tooth brush and clean it up. Also id try just for fun testing it if it goes off with a rads counter. This reminds me of a rock I have that I still don't know what it is. But mine is tiny and green with a bubble inside it with a spiral on the outside.
