Sapphire Sphinx is now available on 50% sale, 1050 gems for a limited time. Or breed one. Breeding time and hatching time 50 hours. Evolution time 32 hours.
Oh my word, I cannot believe I managed to breed one after 6 attempts. Dreading the thought it would take at least more than a hundred attempts with the other 2 gem animals as fails in this combo. I used crystal unicorn and pearl peryton. Breeding time 50 hours. Best of luck everyone.
