You may want to update the notes section for the diamond now:

"The most economic breeding pair for the  Diamond Dragon  is the  Charm  &  Fruitful  combo, due to the minimal coin loss involved (between 382 and 895 coins per hour lost due to being in the breeding den). It has an average time for its common dragon results of 11 and 2/3 hours."
