A few different versions of the emerald dragon are available, long ones, shorter ones and two headed dragons.  

There are some flat ready to print models and ones with heads and tails angled up… that require supports. This allows for a seamless colour change using layer height only which results in all the gems on the top to be one colour.

The ones with lifted in the title, require supports on the head and tails only so use support blockers on the rest of the dragon.

Angle the support blockers (see picture) so the inside of the head doesn't fill with supports.
