as the 6 3/4 fit measured 8 inches, i decided to stick with the small. this was a good call as the bracelet runs big. i have a small (5 3/4 inch) wrist but an average sized hand. the small fits me with a lot of drape. if you have a small wrist/small hand, it may fall off. this said, it is a chunky, funky fun piece. it is very weighty. mine actually weighed 41.5 grams. i ordered the matching earrings as well. they make a great set.
