Nethershards, Vendor

I used “Upgrade Finder” and checked “Broken Shore” in the filters. I searched for “Nethershard”. I got five results, one a new trinket. So I bought 5 Relenquished Trinkets from ‎Thaumaturge Vashreen in Broken Isles. The fifth one was a perfect level 880 trinket for a Holy Priest. It had 1,700 Intellect, and every 1.5 minutes, provides 2,700 boost to my Versitility. Yea!

But it was not in the “Upgrades” list.

Either I do not know how to use it, or it is bugged.

Any thoughts?

Which item is it? Maybe there’s an item that can be had from nethershards that isn’t in our list.
