Wow! I guess I didn't pay close attention to the dimensions of this necklace but it's much bigger than I expected it to be! The diameter of the outermost circle is 2 1/2" and the gorgeous, delicate, lightly twisted chain is 34" long with an additonal 3" extender! I have found that I often don't like necklaces with a rhinestone look because some inexpensive jewelry with rhinestones can look a little chintzy, but this one looks so classy! It looks much closer to Swarovski crystal or a high quality like that. That said, if I wanted something a little more understated, the back of the necklace is also very pretty with just an etched silver texture so it can easily be turned around and worn backwards and looks equally nice in a different, slightly more casual style. This is one of those purchase that I made on impulse not expecting too much and then fell completely in love! I could actually imagine it on women of any age, but it would be an absolutely incredible present for highschool aged ladies to women in their thirties.
