I urgently need to scrape some money together after seriously damaging my car today. DH is furious. The only thing I have that’s of any possible value is my Nan’s engagement ring. It’s a diamond ring from the 1940s and is of incomparable sentimental value to me but I think I’m going to have to accept that I need to let it go. Are standard diamond engagement rings from that era worth anything much? The replacement value when I had it adjusted (I wear it myself) was £1000 but I realise that’s likely to be a lot more than what I’d get if I sold it.
