I'd have to go with a 'Gem' type dragon slayer magic.

Such as Ruby, Diamond, Emerald, Jade, Sapphire, Opal, Pearl, etc.

I've been intrigued with the possibility since the appearance of the Jade/Emerald Dragon in Chapter 300 or 301. Would assume it's not a traditional 'element' type magic and would probably use some type of setup similar to Gajeel's Iron Dragon Slaying - in which he just shoots iron blades from his mouth and changes his body to iron scales
