It took Nicky Hilton three whole weeks to flash her engagement ring in public after her banker beau, James Rothschild, popped the question in Lake Como, Italy. Hard to believe considering the sheer size of the thing, but true. The heiress and fashion designer's bling is an Asscher-cut diamond ring, apparently set on a platinum band. The large diamond is flanked by two trapezoid diamonds on either side and is sure to be flawless allround.
Estimated Value: approx. £250,000
