Before the decimal system, Russia measured purity in zolotniks: 56 out of 96 means 14-karat gold. - **84** — Old Russian silver, 84 zolotniks. 84 out of 96 zolotniks means 875 silver — the same title that is legal in Romania today. - **417** — American 10-karat gold. The historic US minimum gold standard. Above Romania's 333 minimum, but not a legal title here. - **583** — Soviet 14-karat gold. 14 karats is exactly 583.3 thousandths; the Soviets stamped 583, the rest of Europe 585. With a small star beside it, it is a USSR mark. - **835** — 835 continental silver. The German silver standard after 1884. It can be a genuine piece, but it is not a legal title in Romania. - **999.9** — Fine metal, 99.99%. Bullion and modern investment-coin purity. Unusual on ordinary jewelry: fine metal is too soft to wear. ## Letters that say it is not solid - **GP** — Gold plated. A thin layer of gold over base metal. The worth sits in the object, not in the layer. - **HGE** — Heavy gold electroplate. Heavy gold electroplate: thick plating, but plating all the same — the metal underneath is base. - **RGP** — Rolled gold plate. Gold bonded by rolling: thicker than ordinary plating, but the object is not solid. - **GF** — Gold filled. A thick layer of gold over a base-metal core — more than plating, less than a solid object. - **EPNS** — Silver plated over nickel silver. Electroplated nickel silver: a thin layer of silver over a silver-free alloy. Not solid silver. - **EP** — Electroplated. Electroplate: a thin layer of precious metal over base metal. Not a solid object. - **PT** — Platinum, title missing. The mark names the metal, but without a title the purity is unknown: look for 950 or an assay report. - **PLAT** — Platinum, title missing. The mark names the metal, but without a title the purity is unknown: look for 950 or an assay report. - **PD** — Palladium, title missing. The mark names the metal, but without a title the purity is unknown: look for 950 or an assay report. - **PALL** — Palladium, title missing. The mark names the metal, but without a title the purity is unknown: look for 950 or an assay report. ## Frequently asked questions ### What does 925 mean? Sterling silver: 92.5% fine silver. It is the world standard for silver jewelry and a legal title in Romania. ### What does 585 gold mean? 14-karat gold: 58.5% fine gold. It is the most common title for gemstone jewelry. ### What does 375 gold mean? 9-karat gold: 37.5% fine gold, a legal title. 9-karat jewelry is harder and more affordable. ### How many karats is 916 gold? About 22 karats — but 916 is also a legal title for silver, so the number alone does not say which metal it is. ### What does 950 on jewelry mean? Platinum or palladium at 95%: the only legal title for either. The number alone does not say which. ### Why does my jewelry have no stamp? Very small objects are legally exempt from marking — gold and platinum under 1 gram, silver and palladium under 2 grams — and stamps wear off with use. On old pieces, a missing stamp proves nothing by itself. ### Does the stamp prove my jewelry is genuine? No. A number is easy to copy; the law requires three marks — title, responsibility, and state — and only an assay of the metal settles it. ### Is 750 gold or silver? How can I tell? It can be either: 750 is a legal title for 18-karat gold and for silver. Look at the frame of the maker's mark: an ellipse on gold, a rectangle on silver. ## Legal basis Legal titles checked on 18 September 2026 against GEO no. 190/2000, art. 12.
