Is this a meteorite?

Answer

Dear Anita

This website already contains many rocks that turned out not to be meteorites. Your stone unfortunately falls into the same category. Based on the shell-shaped fractures on the surface, it could be a limestone or quartzite. If the surface fizzles with diluted hydrochloric acid, it is a limestone. If the stone scratches on steel or glass, it is probably a quartzite or possibly a fine quartz sandstone. Based on the appearance of the stone alone, there are also other possibilities. The brown color suggests a fairly high iron content, which means that the stone can also be a bit heavy.
