Heavy Metals

So I've been thinking of how to get this ring fixed. According to the silver market, platinum is up by like 12+%. OUCH! I'm just gonna have to go hunting for jewelery places and ask questions. Also the ring is some kind of antique so I don't know if beefing it up and getting it sized will affect its value... Although that does'nt matter to me really I guess....It's not like I'm gonna try and sell it ever.
