986

Ducat gold (986) · 98.6% pure

986 means 98.6% pure gold — “ducat gold”, a historic near-pure German standard tied to the old ducat coinage. Struck as “986”, it's almost pure gold: deep-coloured and very soft, encountered mainly on antique and coin-related pieces rather than modern jewellery.

The reason

Why 98.6%?

986 (Dukatengold) was the fineness of the old ducat coin — near-pure gold — and survived as a recognised standard in the German tradition.

At 98.6% it's almost pure: soft, richly coloured and mostly seen today on historic pieces rather than everyday jewellery, where harder alloys make more sense.

A reference guide, not an authentication service. The same number can appear on different metals, and the mark beside it varies by country, date and maker — consult the relevant assay office or standards body for definitive identification.
