My now son-in-law is a science nerd (and soon to be medical doctor) so the science behind lab diamonds fascinated him. He also had a professor at OSU that is able to produce these (but not commercially), but in turn, did steer him to a discrete jeweler in Columbus that deals in them. When he and our daughter started discussing engagement rings, they were in agreement on the "no blood diamond" part. I can and do appreciate this too plus I'm aware how the diamond market is an absolute racket and manipulated by a small group.
That's when I decided to replace the engagement ring of my wife's that one of our kids lost many, many years ago....
A perk for me too !
