If it's a bachelor/masters sized diploma, you can get an inexpensive "document frame" for it from Michael's. I believe mine was about $10 a few years ago without sales or coupons, and it's still solid and sophisticated looking. Sure, the college's frames may look nice and flashy, but they are SO expensive and don't give you anything you wouldn't get from a <$20 frame (and this is from someone who worked at a university bookstore and sold those darn frames for three years).
