|BELT COLOURS - dark green and black|
As far as I know it was authorized for wear after St Patricks Day, 2011, the buckle is similar to the cap badge, the winged harp is surrounded by a shamrock wreath meeting at the top through the St Edward crown, it differs from the capbadge in that in the buckle, there is a shamrock wreath and the crown is not attached of the harp.
I'm not sure of the correct name for the shade of green, but it is flanked by thin black stripes at the edges.
