Chelsea Clinton Engagement Ring?

Turns out those discredited rumors of a possible Chelsea Clinton wedding last summer were mostly just premature: Chelsea Clinton has become engaged to her longtime boyfriend, Marc Mezvinsky.
The couple sent an e-mail to friends Friday announcing the news, saying they were looking at a possible wedding next summer.
Has Chelsea Clinton been spotted using an engagement ring. How nice is the engagement ring she got?

I want to see her engagement ring too. With all the money Chelsea's boyfriend has she must have got a really beautiful and expensive engagement ring.
Chelsea and her civilian beau, Marc Mezvinsky, are said to be spending close to $1 million on the wedding. Mezvinsky, 31, works in Wall Street and his dad is former Iowa congressman Ed Mezvinsky. A source reveals "Chelsea hasn't even admitted that she's engaged to Marc, but that's not stopping her from planning a wedding. She's always dreamed of having a special wedding, and these days that could set her parents back a million dollars, but they'd give her anything her heart desires for the event." No definite wedding location has been set, though an insider says that "Hilton Head is a good bet because that's where she met Marc in 1993 at a Renaissance Weekend, an annual event for heavy-hitters that their families attended."
