I’ve thought “possible scam” since I first heard of it and saw the prices. Even if they give you a genuine diamond, not a cz, they’d make a buncha bucks. But, let’s assume, for the sake of the OP that it’s genuine. I haven’t asked hubby, but I’m thinking we’ve got better things to do with that kind of money than to turn each other into gemstones. If he dies first, I’ve got gemstones to remember him by: Over the years, he’s given me five pieces of nice gemstone jewelry.
Oh, also, my religion wouldn’t allow this to be done with me. Hubby, however, is an atheist, so that wouldn’t come into play.
