Wonderful wedding band,5mm thick.5.4 grams, size 6.75. The design goes all the way around so if it needs to be sized, then the design won't go all the way around. This fantastic ring is part of the stock from my father's store. This ring is new old stock, and is probably 25-45 years old. These are high quality rings--he had a fine jewelry store-Englewood Jewelers in New Jersey, selling Rolex (he was an authorized dealer), Movado, Concord, Omega, LeCoultre, etc. Check out my feedback--my customers love the jewelry
