When you are sorting through old jewelry with the intention of selling, one of the most important questions you can ask about each piece is: is this solid gold, or is it gold-filled? The answer has a direct and significant impact on whether a coin shop or precious metals dealer will purchase the item. At American Gold Buyers, located at 1178 Woodruff Road, Greenville, SC 29607, we buy solid gold of all karats but do not purchase gold-filled, gold-plated, or gold-vermeil items. This post explains the key distinctions so you can walk in the door with a clear picture of what you have. Call us at (864) 631-1000.
What Is Solid Gold?
Solid gold jewelry is made from a gold alloy throughout the entire piece. The term “solid” does not mean pure (24K) gold — it simply means the gold content is consistent from surface to core. A 10K solid gold ring contains 41.7% gold throughout the entire ring, not just on the outside. Similarly, 14K and 18K solid gold pieces are alloyed throughout. Solid gold is identified by karat stamps: 10K, 14K, 18K, 22K, or their European fineness equivalents (417, 585, 750, 916).
What Is Gold-Filled?
Gold-filled jewelry has a layer of solid gold alloy permanently bonded to a base metal (typically brass or copper) through heat and pressure. By U.S. Federal Trade Commission regulation, gold-filled items must have a gold layer that constitutes at least 1/20th (5%) of the total item weight. Common stamps include “1/20 14K GF,” “1/20 12K GF,” or simply “14K GF.”
While gold-filled contains substantially more gold than electroplated items, that gold is still an outer layer bonded to a base metal core. Recovering the gold from gold-filled jewelry requires a refining process that is not cost-effective for most retail precious metal transactions. As a result, most dealers — including American Gold Buyers — do not purchase gold-filled items.
What Is Gold-Plated?
Gold-plated (also called gold electroplate) has only a microscopic layer of gold on the surface — typically just 0.5 to 2.5 microns thick, which is a fraction of a millimeter. The gold content is negligible. Common markings include “GP,” “GEP,” “HGE,” and “RGP.” Gold-plated items are not purchased by precious metal dealers.
What Is Gold Vermeil?
Vermeil is sterling silver (925) with a gold plating layer. FTC regulations specify that the gold layer must be at least 10K and at least 2.5 microns thick. While vermeil has a sterling silver base with some real silver value, the gold layer itself is negligible, and many dealers purchase vermeil based solely on its silver content — or pass on it entirely.
Practical Identification Tips
Before visiting our shop from Greer, Simpsonville, Mauldin, or anywhere else in Upstate South Carolina, examine your pieces with a magnifying glass in good lighting:
- Look for stamps on clasps, inside ring shanks, or on the back of pendants
- Solid gold stamps: 10K, 14K, 18K, 22K, 417, 585, 750, 916
- Gold-filled stamps: GF, 1/20 14K GF, 1/20 12K GF
- Gold-plated stamps: GP, GEP, HGE, RGP
- Absence of any stamp on a gold-colored item: likely plated or base metal
When you are uncertain, bring the piece in. We test every item before making any offer, at no cost to you.
Why This Matters for Sellers
Understanding the distinction between solid gold and gold-filled can save you from disappointment when you visit a dealer. It also helps you focus on the pieces that actually have monetary value. Many sellers are surprised to find that items they assumed were plated — old chain necklaces, thick rings, heavy bracelets — are actually solid gold and worth meaningful sums.
