Social Media Widget Genericons – no Google ?

I am using the social media icons widget for my front page on a theme that supports only one menu.

I can (obviously) install a plugin which will give me sharing icons to use in a widget, but why should I do this when Jetpack has the functionality built in?

That being said, there doesn’t seem to be support for a google+ icon. Is that correct? Is there a way I can get a google+ icon added to the group?

Thanks for any help.
