As you can see when viewing Yahoo's analyst history, the most recent entry is Jan 12, 2012; not sure if the 17.50 price target data is as stale.
Bloomberg (subscription terminal) shows 9 firms covering DMND with all but one chirping in since 6/10/13.
12 Month target: 17.00
HIgh target: 20.00 (2)
Low target: 14
All, of course, FWIW!
