Russian Gold Marks Look Nothing Like Western Ones

A small stamped number inside a ring looks like a size mark. Most people walk right past it. That number is actually a purity code — and whether it follows the Russian system or the Western system changes everything about how pure that gold really is.

The Two Systems

Don't Speak the Same Language

Western gold uses karats. A stamp that reads 750 means 18 karat — 75% pure gold. A stamp that reads 585 means 14 karat, about 58.5% pure. Those numbers are parts per thousand, called millesimal fineness. Clean, logical, and used across North America, Western Europe, and most of Asia.

Russian gold uses zolotniks. A Soviet-era ring stamped 583 is actually Soviet 14 karat, a slightly lower purity than Western 585. The difference is about 0.2 grams per 10 grams of metal — small, but real. When you're selling by melt weight, every decimal counts.

The Soviet Star Is the Giveaway

Nobody Expects

The biggest difference isn't the number — it's the shape around it. Soviet gold made between 1958 and 1994 carries a hallmark shaped like a pentagon with a star and the head of a worker facing right. That tiny embossed figure is called the "kokoshnik mark" in some circles, though technically the star-and-worker punch is distinct from the later kokoshnik woman's-head stamp used after 1994.

Western gold has no figure inside the stamp. You might see a maker's mark, a fineness number, and sometimes a country code — but no portrait, no star. If you see a tiny human profile stamped into gold at A-1 Trade & Loan on Commercial Drive, you're holding Russian or Soviet-era metal, full stop.

The 585 Versus 583

Confusion

Here's something even regular gold sellers miss: Soviet jewelry stamped 583 is not the same as Western 585, even though the numbers look nearly identical. The Soviet standard was set slightly lower on purpose. Post-Soviet Russian gold shifted to 585 in the 1990s to harmonize with international markets, so a piece stamped 585 with a Russian hallmark is actually post-1994 production — newer, and at full Western purity.

An engraved wedding band with Cyrillic text inside, stamped 583, is almost certainly Soviet-era. One stamped 585 with the kokoshnik woman's-head mark is post-Soviet Russian. Both are real gold. The age and origin tell you which.

Where the Stamp

Lives on Russian Pieces

On Western rings, the purity stamp usually sits on the inner shank — easy to find with a loupe. On Russian and Soviet rings, the hallmark is often on the inner shank too, but it's smaller and packed tighter. The pentagon shape is narrow. The worker's profile is about a millimeter tall. Under a 10x loupe, it resolves clearly. Under bare eyes, it looks like a smudge or a jeweler's scratch.

Russian earrings usually carry the stamp on the post or the clasp back. Russian chain links occasionally skip the hallmark entirely on very fine chains, since the links were too small to stamp without distorting — those pieces get tested by acid or XRF, a handheld scanner that reads elemental composition without scratching the metal.

What Purity Marks Don't

Tell You

Neither system stamps for weight. A Soviet 583 band could be 3 grams or 12 grams. Melt value lives in the weight, not the hallmark. The mark confirms what the metal is; the scale tells you what it's worth. A heavy plain Soviet band with a worn 583 stamp will beat a flashy hollow Western 750 pendant almost every time when the scale settles.

Before you bring any gold piece in, flip it under a strong light and look for a portrait inside a geometric shape — that's your Russian indicator. Then weigh it on a kitchen scale and check live gold spot price at kitco.com. Multiply grams by spot price per gram, then apply the purity fraction. That number is your floor, regardless of which country stamped it.
