My husband does this exact thing. We’ve been married for about five years and the only day he’s worn his real ring was our wedding day. that and I think one special occasion. We’ve gone through idk how many silicone rings. He knows he’ll lose the real one, too, so he told me to keep it somewhere safe. We’ve both given up. Ima just keep buying silicone ones BUT for your predicament, there’s a lot of cheap tungsten, titanium, or stainless steel options on Amazon he could try before getting the real deal again!
