I’ve been married 4 1/2 years and am on Wedding ring No3.
The first one was Tungsten Carbide – it is at the bottom of a lake (long story, but it flew off when I threw some bread to the ducks)
The second was also tungsten, but it cracked after I whacked my hand at work.
My current one is Ti, I don’t wear it much – this is due to having to hacksaw my mates wedding ring off after he caught it on the roofrack of his Landrover and ‘degloved’ his finger (google it) while we were in the middle of the Sahara Desert…
I only wear it when the wife and I go out at weekends now..
