At least people can tell their story I suppose, while a diamond cannot really once mounted on a ring (I guess you can get some certificate that tells a story, but it is not something obvious when looking at the ring).
but it does not seem visible to the naked eye when looking at jewelry... I guess with more lab made diamonds we will come to appreciate the geological beauty of it, and have bigger diamonds for the same price.
Note: my engagement ring cost $12.00 on Amazon: https://www.amazon.com/TIGRADE-Titanium-Polished-Wedding-Com...
