What Does a 417 Gold Stamp Mean?
The small 417 gold stamp on a piece of jewelry is one of the easiest ways to determine its purity.
In a nutshell
A 417 stamp on gold jewelry indicates the piece is 10K gold, containing 41.7% pure gold and 58.3% alloy. It uses the millesimal fineness system, which measures gold purity in parts per thousand instead of karats. While functionally the same as a 10K mark, 417 is more commonly used internationally and is often found on durable, everyday jewelry like rings, chains, and bracelets. 417 jewelry has resale potential because it is 41.7% pure gold.
Why 417 Gold Stamp Instead of 10K?
What is the difference between a 10K vs. 417 stamp? It’s pretty much the same thing.
CIBJO (the World Jewellery Confederation) explains that gold may be described either by caratage (as the US knows it, “karatage”/karats) or by fineness.
The 1972 Hallmarking Convention, also known as the Vienna Convention, established this system for testing and marking precious metals, which is recognized worldwide. This means that certified pieces can move between member countries without needing to be marked again.

For example, with gold at $ 136.51 per gram, a gram of 417 gold contains approximately in gold content before any dealer margin or refining deduction.
Should You Sell 417 Jewelry?
Broken chains, single earrings, and pieces that have not been worn for years can still hold significant value. Gold remains valuable even if a clasp is broken. Additionally, “old” or “damaged” does not always mean scrap. Pieces with gemstones, recognizable maker’s marks, or collectible designs may be worth more than their melt value.
For pieces with resale potential, Alloy’s Double Pay program allows sellers to capture a portion of the upside, offering an additional 25% of the profit when resold.
When selling, it is important to work with a reputable buyer who tests gold using standard methods (touchstone, XRF, or fire assay), explains the results, and bases offers on verified purity and weight. A clear breakdown of the piece, including weight, fineness, market price, and deductions, should be provided.
