Bring on the bling!

Nicky Hilton hasn't been shy about flaunting her blinding sparkler since her engagement was revealed earlier this month. And now, Kathryn Clark from Eshed Diamonds is giving E! News the breakdown on Ms. Hilton's massive rock.

"The carat size looks between 6 to 8 carats, and the shape looks square, which could be a Royal Asscher Cut," Clark dished of the massive rock.

As for color and clarity? "It looks white, which means it's probably a collection GIA—meaning either D, E or F color, and most likely a VVS clarity minimum." In plain English, it's a really nice diamond.
