Pyritized Ammonite Negative and Sterling Silver Ring
Pyritized Pleuroceras Ammonite Negative (Germany) and sterling silver ring. Approximate dimensions are 3/4"L x 5/8'W. Current ring size is a 7.
These are not actually fossils; they are the imprints of the places where ammonite shells rested. These imprints became impregnated with pyrite (hence the term pyritized), and they are the negative image of the shell.
**All rings can be sized unless otherwise noted. A small up charge may be applied for sizing up or down.
