It's tough, you have to chase it. I almost had the achievement, and then the rain and ironwood dragons were released. I was able to obtain them quickly, so I earned the achievement just in time before the new gem dragon came out. Just keep plugging away and hope for a long enough lull in the releases to get caught up.
