I think the lack of those points is due to the fact that it isn't great lithic material and the natives here had an abundance of good and varied stone.
Most if not all of my Quartz points come from faceted crystals some of the cores are large and lot of small crystals that have been broken off of clusters . I have a large number of well made rock crystal points . Here's a large crystal from a couple of days ago .There may be some confusion in terms here. Quartz crystal is one thing. Crystalline quartz is not the same thing. In other words, quartz can appear as faceted crystals, both clear and opaque crystals. But you can also have crystalline quartz, which is simply clear quartz. It does not have to appear as a quartz crystal in order to be crystalline(clear) quartz. Gee, that even makes my head spin, lol, but hopefully you get the picture. I could have a big raw chunk of crystalline-grade quartz, but it would not be in the form of a faceted quartz crystal. I don't think they would normally try to knapp a quartz crystal per se anyway. Quite often, on the other hand, quartz crystals might become part of a shaman's medicine bag.....
