Pastel SVG is an icon set based on the popular silk icons found as FamFamFam.com. It uses the same style, so some of the icons are almost identical. Both sets overlap for most icons, but each has ones that are unique to it, that is till I manage to catch up and create all the ones in the silk package.
The biggest difference right now between the two sets is Pastel SVG has more sizes. As the name suggests Pastel SVG was created as a set of SVG files, that were then converted to PNG in various sizes.
You can get the full set from its home page [link]
