Calling it a "diamond" is hysterical and might be a bit of a stretch

. We all know most of the diamond .tv were taken wayback between 2001 and 2004 with a good chunk owned by Future Media Inc

. Just messing with ya. But at this stage in the game I would lable it an educated/good reg with potential. I like it. Would be worth wild to develop it. Congrats on the find! Very brandable and easy to remember single word .tv.
(in case you're wondering, FMA owns the .com- any they love .tv, good luck)
