Ruby's was a favorite haunt for my girlfriends and I when I was in college at Ohio State. Every time I go home to visit my family I drop in there again and check out the new jewelry.
They carry loads of unique cards, jewelry, fun gifts, candles, gag gifts, handbags, umbrellas, etc. All the things you don't really need but like to shop for. It's a small place right on High Street with a pleasant amount of clutter, and two cats that like to sleep on the steps.
Some of the jewelry is a little pricy, but I have bought some of my favorite earrings there - simple, tasteful and feminine pieces of sterling silver jewelry.
I believe they recently opened a Grandview location across from Caribou Coffee as well.
