Gold-filled (GF)
On the label: Gold filled · Plating and finish
What it is
A thick layer of karat gold mechanically bonded to a base (usually brass); by US rule the gold must be at least 1/20 (5 percent) of the total weight, marked 1/20 14k GF. Fifty to a hundred times thicker than plating; does not flake and lasts years.
Plating and finishs: A thin layer of one metal over another. The layer's thickness, written in microns, decides how long it lasts; US law sets minimums for what may be called gold-filled or vermeil.

Clasp & Lens describes materials from the public record and does not appraise, grade or test pieces; what a listing states is the supplier's statement. If a piece causes a rash, take it off; a reaction that spreads or blisters is a doctor's question, and sunglasses are no substitute for impact-rated eye protection where that is required.
