I think it was for the lvl 35 expedition - some item "Stone ?? Orb", to craft it at the stonecutter a number of the shards that drop when you close a portal are needed, and something called "? Heart", which must be crafted, too.
Sorry, I didn't see the English terms, only the German (where a lot of items aren't translated yet, but have names like masterpiece_40_armor) and can't look it up, since it doesn't run on my computer.
The Orb and fragments are BoP, but not all materials that you need to make it are.
