This is a very interesting specimen of glassy brown Scheelite crystals to 3mm and Scheelite coating the Wolframite crystals as an alteration product. You will see this under uv. The matrix is Quartz with some plates of Feldspar(? - not fluorescent). The surprise is a beautiful gemmy micro crystal of green Fluorapatite to 1mm. The crystal has three beveled faces between the prism and pinacoid faces. Sorry, it's a poor photo of it, but you will like it as it is gorgeous. There is also some minor Chalcopyrite.
