The key is to buy wholesale online or you’ll get totally ripped off, the markups at places like Tiffany’s or Bloomjngdales are outrageous and are the biggest reason diamonds have poor resale value. You wouldn’t buy gold at a 10x markup but that’s precisely what people do with diamonds for some reason. Also don’t buy a diamond on credit, my wife and I had significant savings and no debt so it wasn’t like the diamond hurt our finances.
Of course everyone is entitled to get whatever stone (or no stone) they want! Diamonds seem to be falling out of favor so the article above doesn’t surprise me. I would put some blame on the diamond industry being too greedy, selling at outrageous markups and telling everyone a proper diamond should be “X months salary” where X has gone up by 1 every decade.
