What Is Petoskey Stone Pendant Worth?

The typical price range for Petoskey Stone Pendant is $75 - $82 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Clarity and definition of the hexagonal coral structure within the circular cabochon cut.
• The weight and craftsmanship of the sterling silver bezel setting.
• Overall condition of the stone's surface, specifically the absence of chips or dull spots in the polish.
• The provenance of the stone, specifically its origin from the Great Lakes region of the United States.

How to Identify Petoskey Stone Pendant?

• Look for the distinct six-sided 'honeycomb' pattern characteristic of fossilized Hexagonaria percarinata coral.
• Verify the '925' or 'Sterling' hallmark on the silver bezel or bail to confirm the metal quality from the 1990-2010 period.
• Check for a smooth, high-gloss polish on the stone which reveals the dark 'eyes' of the fossil when dry.
• Examine the stone for natural calcified inclusions that distinguish genuine Michigan fossils from resin imitations.

History of Petoskey Stone Pendant

Formed over 350 million years ago during the Devonian period, these stones are actually fossilized rugose coral. Once part of a warm, shallow sea covering Michigan, they were later spread by glacial activity. They were designated as Michigan's state stone in 1965.
