what does a stamp 750 CB on an italian gold bracelet mean?

A stamp of 750 on an Italian gold bracelet usually means the piece is 18 karat gold , or 75% pure gold. The CB part is most likely the maker’s or manufacturer’s mark, identifying the jeweler or workshop that made it.

What the marks mean

• 750 = 75% gold content, which is the standard Italian fineness mark for 18K gold.

• CB = a maker’s mark or brand code, not the gold purity itself.

• If the bracelet also has “Italy” or a star symbol, that usually supports that it was made under Italian hallmarking rules.

What it does not prove

• The stamp alone does not guarantee the bracelet is solid gold in every case; counterfeits exist, and markings can be copied.

• If you want certainty, a jeweler can test the metal with an acid test, XRF test, or by checking the hallmark details against the maker mark.

Practical read

So in plain English: 750 CB on an Italian bracelet most likely means “this is an 18K gold piece made by a specific maker marked CB”. If you want, I can help you interpret any other marks on the bracelet too.
