Herkimer Diamond Bracelet Value Guide

The Herkimer Diamond bracelet is a prized collectible featuring unique double-terminated quartz crystals sourced exclusively from Herkimer County, New York. These pieces are highly sought after for their natural 18-facet geometry and exceptional clarity that mimics genuine diamonds.

What affects the value of Herkimer Diamond Bracelet?

• Clarity of the quartz stones, with 'water-clear' specimens commanding the highest market prices.
• The number and size of the individual crystals integrated into the sterling silver bracelet design.
• Overall condition of the silver setting, including the presence of original patination or designer maker's marks.
• The structural integrity of the crystals, as stones without internal fractures or 'rainbows' are more valuable to collectors.

How to Identify Herkimer Diamond Bracelet?

• Verify the presence of double-terminated points, meaning the quartz crystals naturally taper to a point at both ends.
• Check for 'anthraxolite' inclusions, which are small black carbon spots often found within authentic Herkimer quartz.
• Look for a '925' or 'Sterling' hallmark on the silver setting, consistent with quality American-made specimens from 1970 to the present.
• Examine the stones for natural facets; unlike cut gemstones, these should show raw, unpolished surfaces formed within dolostone vugs.
