I think that random keepers is way easier to come by than a massive supply of keepers. I have many variations of keepers, that vary not just in color and tactile sensation but also how aggressively they cut, as with all of my keepers leave a great shaving edge. I am completely drawn in by the thrill of the hunt and continue to keep looking even though I have a good stack of beauties. If all I wanted was one great stone I could have given up a while ago, but I want to keep finding more. It's like a whole new version of HAD. I have many stacked and graded by color, some have been tested, some are presumed to be like others based on appearance. Oddly most are variations of green. It isn't even a common rock color here, I doubt is it is anywhere. I did read on a geology web site what makes the rock green but did not manage to retain that tidbit.
