More big diamond news

One of the world's finest blue diamonds, the Oppenheimer Blue, is going up for auction in May. It's expected to get bought for 26.5 million and 31.3 million pounds ($38 million and $45 million dollars).

It's going to be up for auction along with the blue De Beers Millennium Jewell 4 Diamond, which might go for 25 million pounds (around 35 million dollars).

I don't think I'll be bidding on either. It'd be nice to see them on display, though.
