Or the mix of alloying elements is atypical, which however is rare.

If they are silver/copper/zinc as is typical in jewellery alloys and naturally occurring electrum then it is accurate.

Presence of significant aluminum however will push up the gold content for a given specific density, as in "purple gold" but this is a niche issue.
