Celebrity engagement rings are unsurprisingly getting bigger and bigger (um, have you seen tennis player Caroline Wozniacki's massive bauble?). As the diamonds increase in size, obviously the price tag appreciates handsomely.
Lucky for the rest of you fellow Hollywoodphiles who are obsessed with checking out the latest and greatest A-list ice (Paris Hilton's 20-carat stunner, for example), we compiled a list of some of the most expensive celebrity engagement rings to date. With prices ranging from $500,000 to the grand prize of $10 million, these sparkling stars (and even one famous royal) have accumulated quite the covetable jewelry collection—and we have the pics to prove it.
So, whose big-time bling ended up on top? Without further ado, we present 19 of the most expensive celeb gems—from least pricey (albeit still mind-bogglingly costly) to most.
