If the gold allergy or as Ralph put it "all metal allergy" is true that means he is damned to an early death. Implants like pacemakers (which Ralph will need in under 10 years) have gold tipped leads so it wont corrode inside the body. Really that goes for any medical implant with exposed metal. An allergy to all metals would also mean no hip or knee replacements because titanium. So the second his body fails to the point of needing repair he will be bed bound until death. Now Ralph also wears his Apple watch 24/7 which has a metal back. Ralph also spent 3-4 days with an IV in his arm during Portugal one. Top it off he had a metal mesh on his orbital how did his eye not just stay swollen shut? Somehow his magic allergy is just to that ring.

Speaking of ring there is a zero percent chance that is a $15k ring even if it was made of what he claims. $2k per carat of diamond and the band isn't more than $1k. So tops that is $7k + labor if it was made today. If Ralph put any effort into May's ring he would have know basic stuff like that from talking to a few jewelers. Instead both were probably pawn shop or thrift store buys.
