Breed a Crystal dragon with a Cactus dragon.
Peridot
Either buy it for 1,425 gems or breed it using the cactus dragon and the crystal dragon in the breeding cave.
The peridot dragon is a limited edition gemstone dragon. It is available during the month of August. The most successful way of breeding a peridot dragon is cactus + quartz. This is hinted at in the description of the dragon. It can be bred in the breeding cave or the epic breeding island.
