Petoskey Stone Pendant Necklace with Charm

Petoskey Stone from Michigan, handcrafted into a cabochon with a drilled hole.  Pendant has a sterling silver jump ring with a 10 x 14 mm sterling silver snail charm. Includes an 18 inch, rhodium-plated sterling silver 1.0mm box chain with clasp.

Rhodium plated silver is sterling silver coated in rhodium to make it whiter and brighter. Silver is a softer metal, so rhodium protects it from scratches or wear. Solid silver is too soft to be fashioned into jewelry, so it contains 92.5% silver and 7.5% of other metals like copper, nickel, or a combination of the two. The traces of copper and nickel in sterling silver cause tarnishing. Adding rhodium plating prevents this from happening.

Stone measures approximately 18 x 25mm.
