White gold stamped 583

[BearFluff]

Which countries might white gold be from if it's stamped 583 and made during the Art Deco period?

I know that 583 means 14k gold, but if it was American I assume it would be stamped "14k". Apparently European or Russian gold is marked 583. I've done some research and it's obviously not French as they use pictures to stamp their gold, not numbers. It's not British as it would be stamped "14ct". There are none of the little pictures that supposedly were stamped on Russian gold. Some countries didn't even make 14k gold at that time!

Does anyone know which countries actually manufactured 14k gold in the Art Deco period and stamped it with 583? There's no border or anything around the stamp, and no pictures, just the numbers.

Are you sure the stamping doesn't read 585? That's a designation for 14K gold. I don't know which countries mark their pieces this way, but I do see it occasionally.

No, it is definitely stamped 583.

I would guess 583 to be Soviet. At least this website claims so: http://www.jewelry-hallmarks.com/precious-metal-purity/gold-purity-hallmarks/russian-and-soviet-gold-hallmarks/
Also, I have inherited a Soviet rose gold watch and earrings, both are marked 583, and there's a pentagon mark before the number.
