There seems to be no real standard in Oz anymore - we used 9ct and 18ct, then 375 and 750 (which just confused people) and today most stamps are 9K and 18K.
No reason that KT would be a problem and G is maybe the stamp of the manufacturer???
Heft the ring - if it feels too light - worry
As far as the weight goes, I honestly can't tell.
I sent an email asking them what it stood for.
