Xcursor.size: 64
(Could also use 16, 32, 48, or 64)

Org - Gnome - Desktop - Interface
Change cursor-size to match earlier size
Reboot

Please note this won't work with the KDE Oxygen cursors

Tutorial on how to change Mouse Cursors in Gnome 3 with Ubuntu 11.10 and 12.04. I show you how to get the fancy KDE Oxygen coloured mouse cursors selected, but the same also applies for any other X-Cursor Theme.

Install:
gnome-tweak-tool
oxygen-cursor-theme
oxygen-cursor-theme-extra

Open Advanced Settings (gnome-tweak-tool)
Select new cursor theme

Open Terminal (Ctrl+Alt+T)
sudo update-alternatives --config x-cursor-theme

Press Alt+F2
compiz --replace
(Alternatively reboot if compiz --replace doesn't work)

To undo the changes simply repeat all the commands above but choose DMZ-White Cursor theme.
