Whether I agree with the suggested effects or not, I'm just going to add this to your suggestion:
Give the fury 4 charges. Once a charge is used, it becomes untradeable and can only be recharged for 10k tokkul per charge. When it runs out of charges, it crumbles to dust. Apply the same concept to the ring of stone, but give it a different operate effect.
To clarify, they can only be traded as a Fury(4) or Ring of Stone(4), much like how rod can only be traded as a Rod of Ivandis(10).
It will serve as a good way of removing the excessive amounts of onyxes, furies, and stones.
