11-carat Ekati diamond goes on display at Royal Alberta Museum

From the picture it looks like a fairly cool specimen. It's not cut, and it sounds like it wouldn't be any good for cutting anyhow, but its still a cool looking gem.

The 11-carat addition’s now on temporary display with the museum’s mineral exhibit “which includes a gem collection featuring most of the major gemstone families and some of the more unusual types of gemstones. We try to have both rough and cut examples. One thing we didn’t have was a large, display-quality rough diamond, which seemed like an oversight considering that Canada produces them.”
