the most exspensive thing you ever bought

Other than my townhouse, my car for sure. Over the years, probably furniture, travel and cookware. Otherwise, in one swoop: a diamond and sapphire cocktail ring in white gold. It's so amazing and I wear it every day (my right hand ring...yeah!!)
 
I'm quite sure it's my laptop... But I'm buying an appartment as soon as I find something that suits my needs, and although my parents pay for it and I will pay them back, it will still be the most expensive thing I'll probably ever buy.
