ik denk dat cetas een internationale juweliersorganisatie is , die het goudskeur onder/bij zijn merknaam in het juweel slaat.
375 is the marking for 9 carat gold. Usually vintage European will have this marking.
The 220 hallmark on jewelry means it is a commercial bronze alloy.
The 833 marking on gold signifies that it is 833 parts pure out of 1000. Translated to karats this would be 20kt, a popular purity used in Portuguese jewelry.
14 Karat Heavy Gold Filled(plated).

On a gold ring the stamp 585 is meant to indicate that it is 58.5%, or 14 karat gold. However, I urge anyone wishing to buy jewelry to be very careful when judging gold by the marking. If you are dealing with a reputable jewelry store or jeweler, you are probably safe.
Early Swarovski Jewelry was marked SAL
Gold jewelry in Portugual must by law be 19.2 karat pure, there fore the marking of 800 translates to 80% gold, or 19.2 parts out of 24 (24 parts being 24 karat gold, 100% pure). A lot of European gold jewelry is marked 750, which ranslates to 75% gold content, or 18K, 18 out of 24 parts gold. Gold in the US is typically 14K or 58.5% gold, which is represented by the mark 585, 417 is 10K, 41.7% gold. Hope this helps.
