Have You Ever Tried to Sell a Diamond?

Before I asked my my girlfriend, now wife, to marry me I had read much of this history. In fact, my wife and I would have both been okay with a stone other than diamonds - she likes white sapphire for instance. However, in the end I still bought her a diamond ring because of what our families would think. Didn't go crazy, but it is a very nice ring that she gets compliments on. It is jewelry with some symbolism and not an investment. Nor is my really nice mechanical watch. Sure, it's worth something but that is something less than what was paid for it.
