I happened to catch a glimpse of Kate Hudson's engagement ring on the Today show a few days ago and couldn't help but gape. It's enormous, naturally. Hudson's platinum-set ring with an emerald-cut diamond and tapered baguettes on the side is approximately nine carats and has an estimated value of a whopping $200,000. But that's not the only reason I'm smitten. This type of engagement ring style is classic and timeless.I definitely wouldn't turn my nose up at a more petite version of this stunner. On the heels of the Royal Wedding (which I've DVRed and am waiting until tomorrow to throw a viewing party), I thought I'd share some eye candy suitable for a royal.
