What dragons are best to get large gems??

Mainly the black gems to craft the large black gems.
I'm breeding my epic diamond with epic night, as I want more black hybrids (I only have two)

Also I think there should be an option to break large gems into smaller ones too

breed leo hybrid x leo hybrid, you can have more Super rare leo hybrids :) trade them to get big black gems :)

Any super or ultra rare dragons will get you large gems when you trade them in.

I found great luck with Diamond and Virtue, or even Light and Virtue, the number of other non-ultra/supers is low for that combination.

I dont like the black gem dragons, they take SOOOOOO long to breed and evolve its like a week before you can even trade them in.

Its too bad that the crafting portal is so light on the dragon options, I have plenty of red gems but that Ruby dragon is not impressive.

Yeah I have like loads of red, blue and green, but I also have a ruby, emerald and sapphire and I have an amethyst...
I just really want the onyx and tiger's eye.... But my main thing I need is 4 large black gems... So 20 small black gems....
