Stay away from Kay Jewelers.....VERY low quality.
I have always been a fan of Jared's...(yes I know the stores are "related", but there is a HUGE difference in quality!)...just gotta be on your toes so that you know what you are getting......what metal do you plan on going with??? Silver? Gold? If doing a bracelet, go 10k, necklace or anything of the like, stick with 14k.
If going white gold, check to see if they have a "plating" warranty, as the white WILL rub off.
If you aren't going to Jareds, make sure whatever you buy is stamped. 10k, 14k, 18k, or 925 if going silver.
