Diamonds when used for industrial purposes are pretty valuable iirc.
A diamond sitting in a ring (read: anywhere other than industrial purposes) is absolutely worthless. No?
Let's start with the diamond ring. We're going to assume a loving relationship that lasts until death. Whoever is wearing the diamond ring is walking around with anywhere from hundreds (poor folk) to hundreds of thousands, if not millions, of dollars (rich folk) on their finger for absolutely no fucking reason!
The diamond serves absolutely no purpose apart from impressing other people (and honestly, if you care about the opinions of people who are impressed by a useless rock then we can't have a rational discussion). Sure this argument can be applied to a great many things in any given home but none of those things concentrate as much money in such a small package.
In any other form of jewelry I can maybe understand it if you plan on selling it later on for more than you paid, or even at a slight loss. Sure, they do look kinda pretty, whatever.
You can tell me that the diamond is a symbol of your never ending love but fuck all that jazz. If my partner doesn't get that I love them from the fact that I'm promising the rest of my life to them then we have issues that no pebble can solve.
So... TLDR version. A diamond that you plan on keeping forever is a worthless piece of rock that some people might have even died for. A diamond that you plan on reselling some day is a needlessly risky investment. Discuss?
Just a quick thing, I see this come up a lot. Don't use this thread to whine about how you are forever alone. If you truly believe that then clearly the poll question wasn't meant for you. Stop being whiny and go ask someone out. The worst they can do is say no.
