Here is a kit of 270 vectors pieces that can be used to create certificate/diploma or simply as decorative elements. Files are in "illustrator 10" (.ai) , "EPS 10" (.eps) so you should be able to use them in pretty much any vector editing software. These are great for print or web design as they scale without any loss of quality.
