Excellent combination piece from the Khibiny Massif in Russia, UNLIKE frankly any mineral combo we have seen at a first glance. I never would have guessed this to be a yellow apatite from Russia, and had never seen the like - it looks exactly like a Brazilian Milarite, in fact. The color is just different, too neon-REE for the usual apatite we see from other places. The focus of this small-cabinet specimen is clearly the cluster of three choice Fluorapatite crystals that are centered perfectly on the main face of the large Feldspar crystal. Lustrous, gemmy, and well-formed, the largest of these crystals is 1.7 cm. The Fluorapatites are laced with fine intergrown needles of Aegirine, which are also growing across the the face of the Feldspar. There are a generous number of 1-2 mm, red Kentbrooksite crystals that add color and mineral interest to this already quality specimen (and is a bonus, because these are VERY good for that species as well: Kentbrooksite is a moderately rare mineral of the eudialyte group). Interestingly, both the Fluorapatites and the Felspar have some level of fluorescence, which raises even more the interest level of this notable piece. Old material, as Kurt bought from the first batches of Russian specimens coming into Germany in the 1980s.
