Real Gold vs Silver Earrings — How to Tell What You're Buying

By Dmitry Strugovshchikov, founder of STRUGA

Real gold earrings and real silver earrings give themselves away once you know where to look. Hallmarks, weight, color, how the metal behaves with a magnet, how it ages — every honest piece leaves the same fingerprints. Counterfeits and gold-plated trinkets dressed up as solid pieces leave different ones.

I run STRUGA out of the workshop on the Indonesian island of Bali. We work in 925 sterling silver only — no gold pieces, no plating, no rhodium. That gives me a clean position to write this guide: I'm not selling you the gold side of the comparison. What I am giving you is honesty about what you're holding.

This is the field manual: every test you can run before you swipe a card, every hallmark you'll see, every red flag that should slow you down. By the end you'll know whether the earrings in front of you are real gold, real silver, gold-filled, gold-plated, or costume metal — and what each one is actually worth.

- Real gold earrings vs real silver earrings: gold is karat- or millesimal-marked (10k/14k/18k/22k/24k; 417/585/750/916/999), silver is 92.5% silver + 7.5% copper stamped 925 or STERLING.

- STRUGA works in 925 sterling silver only — no gold, no plating, no rhodium.

- Neither real gold nor real silver is magnetic. Density settles the rest: 18k gold 15.58 g/cm³, 14k gold 13.07, sterling 925 10.40, brass 8.40. An 18k hoop outweighs an identical sterling hoop by about half, not by double — the doubling figure compares pure metals, not the alloys jewelry is made of.

- If a gold earring costs less than the spot price of its own metal weight, it is not solid gold. Gold and silver both have a price floor; counterfeits do not.

- Eight tests in order: hallmark, magnet, weight, color, 10x loupe, acid, ice (silver only), ring (silver only); most fakes fail at step 1 or 2.

- Gold-filled (1/20 14k GF) is a thick bonded layer lasting 10–30 years; gold-plated is 0.5–2 microns and wears off in 3–24 months.

- "German silver," "Nickel silver," "Alpaca," and "Tibetan silver" contain zero silver; sterling silver develops a grey patina with age — STRUGA calls this Living Silver.

How much does a real sterling silver earring weigh?

Every hoop figure you find online is modelled from a formula. These are weighed on our own bench, and you can hold them against whatever is in front of you.

Across the STRUGA earrings collection, all 925 sterling, single-piece weights run from 1.6 g to 8.0 g. A stud sits at 1.6–3.0 g. A thorn earring is 2.5 g. A double thorn is 7.0 g per side. The heaviest shape in the collection is 8.0 g.

Run those through the density table and you have the gold check. The same object cast in 18k gold weighs 1.50× more, in 14k 1.26× more, in brass 0.81× as much. A 2.5 g thorn earring would be 3.7 g in 18k. A 7.0 g double thorn would be 10.5 g.

So if a seller's "solid 18k" earring weighs what a sterling one weighs at the same size, the metal is not what the tag says. That is the weight test run against measured numbers instead of estimates.

What does "real gold" actually mean?

Gold's density is 19.3 g/cm³. It is the most ductile metal known: one gram draws into a wire about 2.4 km long. It's also too soft for jewelry that takes everyday wear, and so jewelers alloy it.

The karat number tells you what fraction of the alloy is gold by weight. 24 karat = 24/24 = 100% pure, 18 karat = 18/24 = 75%, and 14 karat = 14/24 = 58.3%. The US and EU are primarily 14k or 18k, and Asian markets favor 22k and 24k. The same gold piece in a Dubai souk and a Manhattan jeweler may have very different karat — neither is counterfeit, both are honestly marked, the math simply differs.

The four hallmarks you'll see on real gold earrings:

• 10k or 417 — 41.7% gold, harder, more durable, paler in color. This is the US floor for the word "gold"; the UK floor is lower, 9ct or 375.
• 14k or 585 — 14/24 is 58.3% gold, rounded up to 585 on the stamp; the workhorse standard for earrings and the best balance of color and toughness.
• 18k or 750 — 75% gold, the European standard for fine jewelry, and richer color, softer.
• 22k / 916 or 24k / 999 — high-purity Asian and bullion-style, and beautiful, however, bends if you sleep on it.

Anything stamped GP, GEP, HGE, 1/20 14k GF, RGP, or "gold tone" is not solid gold. Plated and filled pieces are still legitimate — they're simply a different category at a different price.

What does "real silver" actually mean?

Silver's density is 10.49 g/cm³, melting point 962°C, the most reflective metal in existence. Like 24k gold, it's too soft to hold an earring post or a hoop catch. So jewelers alloy it: 92.5% silver, 7.5% copper, and that alloy is 925 sterling silver.

The hallmark you're looking for is understated: 925, sometimes alongside "STERLING" or a maker's mark. On a small earring stud the stamp is sometimes hidden inside the post or behind the back. Use a 10x loupe — every hallmark stamping I've ever sent out is visible at 10x even when invisible to the naked eye. Every earring in the STRUGA earrings collection carries that same 925 stamp — studs, cuffs, hoops — sometimes on the post itself.

Other silver categories to know:

• 999 fine silver — 99.9% pure, used for bullion, ceremonial pieces, some specialty earrings, and softer than 925, scratches more easily.
• 958 Britannia silver — 95.8% pure, the British assay standard.
• 950 silver — 95% pure, occasional in Mexican and South American work.
• 800 silver — 80% pure, common in vintage continental European pieces.

If you see "silver-plated", "silver-tone", "EP" (electroplate), "EPNS" (electroplated nickel silver), or "sterling-look" — it's not solid silver. STRUGA's full reference on this is in our 925 sterling silver authenticity guide; for the alloy itself see the sterling silver complete guide.

Which eight tests tell real gold and real silver apart?

You do not need a lab or an XRF gun. You need eyes, a magnet, a kitchen scale, a 10x loupe, and patience. Run these in order — most fakes fail at step 1 or 2 and you save the rest of the work.

Test 1 — Hallmark and stamp

Look for the karat (10k–24k) or millesimal (417, 585, 750, 916, 999) on gold; 925 or STERLING on silver. On earrings the stamp lives on the back of the post, on the inside of a hoop, on the edge of a clasp, or on a tiny tag riveted to a chain. Marking is not universal, and this trips buyers up. In the US the National Gold and Silver Stamping Act does not require a quality mark at all; it requires that a mark, once applied, be accurate and carry the maker's registered trademark. The EU has no single hallmarking law — compulsory assay in some member states, voluntary in others, none in a third group. The UK is the strict case: under the Hallmarking Act 1973 nothing may be sold as gold or silver without an assay office mark. So an unmarked piece is a question, not a verdict.

What good hallmarks look like: crisp edges, even depth, square-cut numerals. What poor ones look like: smudged outlines, wandering letter spacing, depth that varies between digits, marks that disappear on close inspection.

Test 2 — The magnet test

A strong neodymium fridge magnet will tell you whether there's iron, nickel, or steel in the piece. Neither real gold nor real silver is magnetic. If the earring jumps, sticks, or even leans toward the magnet, it has a base-metal core or filling. Costume earrings with a thin gold or silver coat over a steel post will fail this test instantly.

Caveat: a few non-magnetic base metals (brass, copper, zinc) won't react to a magnet either. A clear magnet result is necessary, not sufficient, so move to the next test.

Test 3 — The weight test

This is the test that catches plated and hollow fakes. You need a 0.01g jewelry scale.

• An 18k gold hoop, 1.5mm wire, 15mm inner diameter — 1.4g per side. That is 0.092cm³ of metal at 15.58 g/cm³.
• The same hoop in 14k gold — 1.2g per side.
• The same hoop in 925 sterling silver — 0.95g per side.
• The same hoop in brass — 0.77g per side.
• The same hoop in hollow plated steel — would weigh 0.4–0.6g per side.

Until this revision the guide printed 1.6–1.9g for that 18k hoop. The figure was computed from the density of pure gold, and a genuine 18k hoop would have failed it. Alloy density is what you weigh against, not bullion density.

If a "solid 18k" hoop weighs the same as a sterling silver one of the same dimensions, it isn't solid 18k. Gold has a density problem you can't counterfeit without expensive heavy alloys. Mind the margin, though: 14k and sterling sit only 26% apart, so measure the dimensions before you trust the scale.

Test 4 — The color test

Hold the piece next to a known reference. A real 24k bullion coin, a real sterling silver spoon, a piece of polished stainless steel.

• 24k gold — saturated egg-yolk yellow.
• 22k gold — slightly paler, still warm.
• 18k gold — clearly warm however, with hints of the alloying metal (copper for rose gold, palladium for white gold, silver for green gold).
• 14k gold — noticeably paler than 18k.
• 10k gold — pale enough that some buyers ask whether it's gold at all.
• 925 sterling silver — bright, slightly cool, and develops a warm grey patina with age. Oxidized silver earrings push that patina to deep grey or near-black on purpose.
• White gold — close to platinum tone because of the rhodium plating, and underneath the rhodium, white gold is yellowish-grey.
• Stainless steel and brass — fakes usually have a flatter, more uniform reflection than precious metals do.

Test 5 — The loupe test

10x magnification. Look at the post-to-front join, the seam where a hoop closes, the back of any stone setting.

A real solder seam is about 0.1mm, slightly different in color from the body metal, deliberately laid. On a plated piece you'll see the plating thinning at high points where polishing has worn it down — a halo of duller metal where the gold or silver is gone and the base shows through.

STRUGA pieces are made by hand at the Bali workshop, so the loupe test is also where you spot honest handwork — microscopic asymmetries in solder beads, faint tool traces along the inside of a hoop, the small irregularity that says a human, not a CNC, finished this. The Bali silver guide covers what to look for in detail.

If you want a reference object for the loupe test, take the Thorn earring — 2.5 g of solid 925, hand-finished solder, the kind of honest handwork this test is built to reveal.

Test 6 — The acid test (use carefully)

Jeweler's acid testing kits cost $15–25 and contain three or four bottles of nitric acid graded for 10k, 14k, 18k, and silver. You scratch the earring on a basalt-colored testing stone, drop one drop of acid on the streak, and read the reaction.

• 10k gold — slight color change with the 10k acid, dissolves in the 14k acid.
• 14k gold — stable in 14k acid, dissolves in 18k acid.
• 18k gold — stable in 18k acid, dissolves in 22k acid.
• Silver — turns milky-white with silver acid.
• Plated metal — fizzes and changes color almost instantly because the acid eats through the thin plating into the base.

This test damages the surface where you scratch, so use it on a hidden spot, not on the front face. If you're not comfortable with acid, take the piece to a jeweler — most will run a free or $5 acid test for a customer.

Test 7 — The ice test (silver only)

Silver is the most thermally conductive metal of any kind — it transfers heat faster than copper, faster than aluminum, far faster than the alloys used for fakes. The test works on mass: a silver bar or a spoon melts a cube visibly faster than a brass reference. On an earring it mostly does not. A 2.5 g stud holds almost no heat to give, so the cube behaves much the same on silver and on plated brass. Use ice on flatware and bullion; on earrings, weigh instead. The test also cannot tell 925 from fine 999 at any size.

Test 8 — The ring test

Old silver dealers dropped coins on stone: real sterling rings with a clear, high chime that sustains a second or two, plated base metal gives a duller, shorter clack. It is a genuine test — for coins and flatware.

Do not do it with earrings. A stud is too small to sustain a tone, a post bends, and a set stone can crack on stone. If you want the sound test on a piece you already own, balance it on a fingertip and tap it with another coin instead of dropping it.

Don't drop precious gold the same way — it dents, and gold's softness is a feature; the ring test is a silver-only trick.

What is the difference between solid gold, gold-filled and gold-plated?

The single biggest source of buyer confusion, and four categories, four price tiers, four very different lifespans.

Category	Composition	Lifespan with everyday wear.	Honest pricing
Solid gold (10k–24k)	Karat-stamped alloy through and through.	Generations.	Spot price + design + maker margin.
Gold-filled (1/20 14k GF)	Thick gold layer (5%+ of total weight) mechanically bonded to a brass core.	10–30 years.	15–30% of solid gold equivalent.
Gold-plated (GP, GEP, HGE)	Electroplated layer over base metal, typically 0.5–2 microns. The FTC floor for plain gold electroplate is 0.175 microns; "heavy gold electroplate" (HGE) must be 2.5 microns or more.	3–24 months on earrings.	Costume pricing.
Gold-vermeil	Plated layer minimum 2.5 microns over a sterling silver core.	2–5 years.	Sterling pricing plus a small markup.

Where buyers get burned: a "14k gold" earring that's actually 14k gold-plated. The "14k" refers only to the karat of the plating, not the karat of the body. The trick is legal in some markets if the seller doesn't omit the GP, GEP, or "plated" qualifier — and is straight fraud where they do.

If a vendor is dodgy about whether something is solid or plated, walk. Real gold sellers volunteer the karat, the weight in grams, and the spot-price math. The same logic applies to silver — solid 925 sellers volunteer the alloy, the gram weight, and the hallmark location.

What is the difference between sterling silver, silver-plated and "silver-tone"?

Same structural confusion, different metal.

Category	Composition	Lifespan with everyday wear.	Honest pricing
Fine silver (999)	99.9% pure silver.	Generations, however, scratches faster than 925.	Spot price plus a small markup.
Sterling silver (925)	92.5% silver, 7.5% copper.	Generations, with care.	Spot + design + maker margin.
Argentium silver (935+)	Sterling with germanium replacing some copper, and tarnish-resistant.	Generations.	Sterling plus a small markup.
Silver-plated	Electroplated thin layer over base metal.	1–5 years on earrings.	Costume pricing.
"Silver-tone" / "Silver finish"	Frequently no silver at all — just a silver-colored coating or paint.	Months.	Costume pricing.
"German silver" / Nickel silver	Copper-nickel-zinc alloy, and zero silver.	Variable — depends on the alloy.	Base-metal pricing.

The marketing terms that should slow you down: "silver-tone", "sterling-look", "Bali-style silver". The word "silver" appearing in a name does not guarantee silver content; the hallmark does.

Why do people choose silver earrings over gold?

The choice between gold and silver earrings is partly tone, partly skin chemistry, partly philosophy, partly budget.

Reasons to choose real gold

• Patina control. Gold doesn't tarnish. A 14k or 18k earring looks identical at year 20 to year 1 if you don't beat it up.
• Liquidity. Solid gold has an immediate resale market at the spot price minus a small margin.
• Allergy-friendly at high karat. 18k+ is primarily gold; the alloying metals are fewer and gentler. Sensitive ears that react to nickel frequently tolerate 18k yellow gold without issue.
• Color. Yellow gold has a warm tone that flatters warmer skin undertones.

Reasons to choose real silver

• Price-to-presence. Sterling lets you buy a sculptural piece at the price of a small gold accent — our Double Thorn earring is that math in metal: 7.0 g of solid 925 per side, a weight that would cost several times as much in 18k.
• Patina as a feature. Sterling darkens, ages and takes on character; because we put no rhodium on it, we call that property Living Silver. Oxidation is the other thing and we keep the two apart: it is a technique, the piece is darkened at the bench and arrives dark. Part of the collection is made that way — the oxidized silver earrings.
• Cooler tone. Sterling reads cooler against pale or olive skin and harder against streetwear.
• Cultural weight. Sterling carries different traditions — Balinese silver work, Mexican Taxco, English Georgian, Scandinavian, and gold carries different ones.

For sterling buyers our full Bali silver complete guide covers tradition, technique, and what real Bali handwork looks like under a loupe.

Material is one of four things that tell earrings apart — the other three.
