More power to Tay Tay. No, seriously, more power to her. She’s taught most of us something new about engagement rings, although the price is confusing. It went from $500,000 to $5m, which wouldn’t be a gap you’d be comfortable with unless you were Travis Kelce and herself. Cubic zirconia, though, it isn’t. That’s for sure. Nor is it lab-grown. It has lots of carats and is a mine-cut, which you don’t need me to explain to you.
