Cannot trade spare black pearl dragon

[pernmagic]

Is it just me but I've tried to trade my spare black pearl dragon and the game will not let me although if I wanted to trade other black x gem dragons it will let me
Any info on why please.... I think I won them on a wheel spin, so not crafted

Gemstone dragons aren't tradable.

There are several others that are not tradable, you'll know which ones when you see the trade button isn't available for them

Thank you both, I should have twigged as I have two pearl and Two light ( whom I knew I could not trade ) and two black pearl so the small ones can do some work by breeding while the tournament it's on ... Pearl x black pearl .... Have 21 hrs so either a poison yuck or onyx .... Worth a try
