Calcified Coral Fossils Five Species Mineralized Specimen

This is five different types of coral that was initially fossilized (petrified into stone) and later mineralized, meaning Calcite molecules slowly replaced the original rock molecules. Apologies for not having an example but if you put light up to any of them, they are translucent as they are made of Calcite. As far as the size, these are not big. They are about an inch across with the biggest one being probably an inch and a half in length. Also, some are white and some are yellowish - just depends on the conditions during the mineralization. (Calcite itself is white or yellow usually.)
