Silver has a daily global spot price. A sterling piece weighing 10 g holds roughly 9.25 g of silver — at $30/oz that's about $9 of metal alone, before labor, overhead, or margin. Listings priced near or below raw silver weight are almost always plated base metal or fake.
Most countries require a fineness stamp (925, .925, STERLING, 958, 999). A missing mark is not always fake, but it is a red flag for modern retail pieces. Antique silver may be unmarked if it predates national assay laws.
Pure silver, sterling, Britannia, Argentium and fine silver are all non-magnetic. If a refrigerator magnet attaches firmly, the core is almost certainly a ferrous base metal — plated nickel, steel, or iron.
These are three legally distinct categories. 'Silver tone' contains no silver. 'Silver plated' has a thin silver layer over base metal. Only 'sterling' (or 925 / 958 / 999) is solid precious metal. FTC jewelry guides prohibit the first two from being sold as 'silver'.
Reputable sellers publish alloy information, fineness, and plating thickness on product pages. Evasive answers ('it's just silver-colored', 'the supplier didn't say') indicate either ignorance or deception. Both should end the transaction.
Authentic sellers show close-ups of hallmarks — either directly on the piece or in a secondary image. If every photo is a plain studio shot with no mark visible, the seller may not have inspected the piece, or the piece may not bear a mark at all.
Sterling silver is near-odorless. A sharp metallic or 'pennies' scent indicates copper or brass oxidation — common when silver plating has worn through to the base metal. Some cheap alloys include nickel (a known contact allergen) that produces a distinct bitter smell on skin contact.
Silver is dense (10.49 g/cm³). A chunky sterling ring should feel noticeably heavier than its plastic counterfeit or aluminum base. Lightweight hollow pieces can be legitimate (hollow tubing), but a solid-looking band that feels airy is suspect.
This is a destructive last-resort test: a drop of dilute nitric acid on a scratched spot turns creamy white on sterling but green on copper-heavy base metal. It ruins the tested spot, so only use on scrap, on a hidden interior surface, or as a professional appraiser's confirmation.
Unregistered marketplace accounts, cash-only transactions, and sellers without returns policies remove your ability to verify claims after purchase. Legitimate silver sellers accept returns, issue invoices with composition stated, and operate through platforms with buyer protection.
If any of the above flags is raised, work through these five steps in order. They move from fastest (free) to most definitive (paid).
Use a 10× loupe. Look for 925, .925, STERLING, 958, or 999. Compare unfamiliar marks in the hallmark decoder.
Silver is non-magnetic. A firm pull means a magnetic base metal.
Silver = 10.49 g/cm³. Measure volume by water displacement, divide mass by volume, and compare.
Fineness (925, 958, 999), plating thickness (for vermeil: ≥2.5 µm), and alloy disclosure should all be explicit. Missing information is itself information.
Local jewelers, gem labs (GIA, IGI, SSEF for gems; XRF gun shops for silver) can confirm alloy in minutes.
