There has been a lot of schorl from Erongo over theist few years, I think this is a good example to illustrate the difference between pieces form "Erongo" and "Rondeklip".  Rondeclip pieces tend to be single crystals, often with cleaner non-compound faces. The majority are somewhat flatter and stubby-- the bulk of pieces on the market over the last couple years have been from a couple massive pockets discovered in that area-- the most frequent associations are with quartz and hyalite opal. This one is from Erongo-- erongo pieces tend to be more elongated, they often have fibrous terminations, and fluorite is a frequent association.  This comes from the same hole as the "lollipop pocket" which is a bit of a marketing misnomer-- that wasn't one small pocket but rather a zone in a long mineralized tube.  You can even see some little "lollipops" on the side of this one-- the sort of thing that when broken off would have been stuck in a Perky box and sold as a thumbnail.
