It's an icon of a bunch of grapes with a short stem still attached. The stem is at the top and cut off at the very top, where there are eight circles evenly spaced representing each of the hanging grapes.
This Grapes icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,800 icons, all in the same style and quality.
