In the end, Iver still forgave Sine--although, strictly speaking, Sine had not actually done anything wrong in the first place.
After all, he had never needed the Water Angel Shard. Even if he kept it, it would not be of much use to him. The Fire Shard, on the other hand, was somewhat meaningful to him.

Anything he earned beyond that belonged to him; and if he lost out, Iver would not reimburse him.
--So, essentially, Iver had found himself a scalper.
As long as the scalper did not run off with the money without delivering the ticket, there was no need to feel sorry about anything--at worst, Iver could simply trade with the other party himself.

--But the Water Shard could genuinely
