With the new diamond hybrids it would be perfect to have a new dragon type named onyx that would be made with diamond/magic mix. It would follow the "diamond" dragon as onyx is a rare rock and in many games onyx takes up a magic type stone. The dragon would be black and look somewhat like the dragon head above nether portals. Let team lava if you think this would be a good idea and if you haven't gotten that ultra rare diamond dragon yet, like my thread named "diamond Dagon package deal".
