It looks like a relatively large stemmed point. The ones with the squared bases are usually referred to as "Bare Island" points. If the stem is tapered down some, also termed constricting stemmed, they can be called "Piney Island" points, which that one appears to be. If the stem is even more tapered/ pointy/constricting, they are often called "Poplar Island" points. That one looks to possibly be made of jasper. JMO
