Hi. Not sure if this is the right place for it but I found these spherical rocks and wondered what type of rock they were? Any rock identification apps I installed were useless. They weigh in at 220 grams and 254 grams and have similar densities of 2.75g/cm³ and 2.50g/cm³. Any help would be appreciated.
