That ring is the pre-Update version (though we should have it in our timeline, we have the post update versions). The quest instead rewards with Vermilion Sky Ring.
That being said, you cannot buy this MQ because PoSky Quests haven't been updated to have MQ function on them. See my bug post here:

Basically you will have to either raid sky or buy the loot rights to these items to complete the shaman FD ring.
