You will need a lot of jewels to unlock the Tier 4 certificate. If you have already unlocked the certificate, you can't return it. However, you can keep breeding for a tier 4 Black Forest for as long as you want to once you get the certificate. You don't have to breed one during the Purebreeders.

If you haven't unlocked the tier 4 certificate, then you won't lose anything by doing the tasks to earn the jewels. The jewels will stay with you for the next round as well. You cannot breed a tier 4 Black Forest without the certificate though, and the certificates will change in less than a week.
