The Bergeon 6675-4 Gold Test Needles are a premium Swiss-made set of four solid gold testing needles designed for professional jewelers and metalsmiths who require accurate, reliable karat testing.

Each needle carries a small square of solid gold in a specific karat, ensuring consistent, trustworthy results when testing gold alloys with acid or touchstone methods.

This set is manufactured by Bergeon, a respected name in professional jeweler and watchmaker tooling, and is made in Switzerland to exacting standards.
