Petosky Stone 3 Strand Silver Box Clasp (SKU 3026)
Petosky stone, which I believe is fossilied coral, comes from Michigan...and is its "state stone", if there is such a thing. This stone was cut and polished in my home studio in Florida. It is mounted on a silver plated 3 strand box clasp finding.
The clasp measures 32 mm x 30 mm including the loops and the cabochon measures 30 mm x 22 mm.
