I love pink and its a pretty ring, but I wouldn't do it for an e-ring. I think colored stone engagement rings are fine, but you want to wear your engagement ring all the time and there's a lot that hot pink doesn't go with. Most blue sapphires are a lot more 'neutral'. Emeralds also look much more subdued than that and more go-with-everything
a pink diamond (while super expensive) could work, because they're usually a much paler pink, which looks more subdued also. But not, I think ,a pink sapphire.
I can't see an older woman with that ring, either. It's not classic enough. It would look good on a twenty-something or thirty something, I think , but not on older than that.
But in the end it's up to you. Get what you and your fiance like.
