Another interesting discussion regarding these crosses. I was going to ask, how does one know if the centre is real gold or not but after studying the cross that started this thread with the later examples posted, which are confirmed as real gold, one can see that the quaility of the external rim of the medallion is different in appearance. You can see the real gold examples are smooth, polished and a slightly different shade from the gilded cross, whereas the first one the rim is the same colour as the rest of the cross and is rough in appearance. Is my observation correct in determining real gold from the 'upgraded' pieces? Rich
