What does 55 on a ring mean?
1 Answer

On a ring, what 55 means varies. If the ring has a large central stone or is set with multiple gemstones, 55 may mean that the stone or stones have a weight of 55 carats. Alternatively, 55 may mark a foreign ring size. In European standard jewelry sizes, a 55 is between a U.S. 7 and a 7.5. Find a large collection of antique, vintage and contemporary rings on 1stDibs.
