This is a beautifully polished 1.5 inch oval Petoskey Stone with a Sterling Silver bail. The drop length is 1.8. A Petoskey stone is a rock & a fossil. It is composed of a fossilized Hexagonaria percarinata. Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges & depositing them in the northwestern (and some in the northeastern) portion of Michigan’s lower peninsula.
