I love my engagement ring, sure it's not practical and we'll never get the money back that was paid for it. Every time I look at it sparkling, I think about my husband, and I think about the rock itself, where it came from, how it was formed, how old it is, and it makes me really happy.

We aren't short of money so the purchase of the ring wasn't a big deal - we would easily spend twice the amount of the ring's value on travel every year.

The ring is diamond and platinum and it's very strong - I've smashed it against all sorts of things, gone canyoning, scuba diving, you name it, and the platinum is barely scratched.

We plan to keep this ring in the family and pass it down through the generations. The sentimentality and 'family heirloom' qualities are also really appealing to us.

I'd much prefer this ring than a rolex, or a gold Apple iPhone for that matter!
