Is it correct for a boyfriend to give a girlfriend a Claddagh ring?

a boyfriend can absolutely give a girlfriend a Claddagh ring.
on the right hand when worn, heart facing out.. means the wearers heart is available – single … heart facing in the heart of the wearer is taken.. on the left hand.. facing in.. married. if out.. i have no idea..
the metal, platinum, for a girlfriend? in my book.. rather pricey,, sterling silver would be just as nice and probably alittle more practical for the ol’ budget.. really it depends on what she likes. i wear silver now.. but hint around to the old man for a platinum one for engagement/wedding.
Probably but I’ve never heard of it before. If they did they’d probably be laughed at though.
