This specimen is one of my favorite of the miniature sized pieces. This one has an stolzite-dusted scheelite octahedron perched on the end of a couple quartz crystals.
I had seen a small group of these at Tucson 2015, and was hoping to get more on this trip. Although the find was small, I was able to come back with a group of pretty good pieces. While these are never especially "sharp", those I saw in Tucson looked especially melted-- the pieces I came back with have well formed scheelites, cleaner (I think) form and a generous coating of the powdery yellow-green stolzite that makes them so eye catching.
In 5 trips to Peru, I was only able to get an example of this material once before-- I was quite happy to have been there at a time close enough to a find to be able to get more.
