What Is Herkimer Diamond Ring Worth?

The typical price range for Herkimer Diamond Ring is $70 - $100 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• The clarity of the quartz, with water-clear specimens commanding the highest prices.
• The size and carat weight of the central Herkimer crystal relative to the silver setting.
• The presence of rare internal features like 'enhydro' bubbles or skeletal growth patterns.
• The overall condition of the sterling silver mounting, specifically looking for minimal wear or tarnish.

How to Identify Herkimer Diamond Ring?

• Verify the stone is double-terminated, meaning it naturally tapers to a point at both ends.
• Check for the '925' or 'Sterling' hallmark on the inner band, consistent with late 20th-century American craftsmanship.
• Look for small black carbon inclusions or 'anthraxolite' which are characteristic of authentic Herkimer quartz.
• Ensure the stone has a raw, unpolished surface that retains its natural geometric crystal faces.
