Post #37 pics are definitely of Herkimer Diamonds (i.e. double terminated Quartz crystals. Post #43 pic is of both Herkimer Diamonds and clear Quartz which be from Herkimer Diamonds that shattered. Herkimer Diamonds can fetch pretty good money on eBay, depending on how clean and clear the crystals are and the shape as well. I see that some have some twins that grew off the sides of some and these are highly sought after as well. We used to find lots of these near the swimming beach on Douglas Lake in Sevier County Tennessee.
