Missouri Flint is well known for making decent knapping material with creamy colors, and it is even known to sometimes carry orb like materials. It can take a decent polish, though it can occasionally have fractures. It is still a pretty neat and unique one to work with!

I do my best to represent the stones with photos. I don't enhance photos, though sometimes brightness and contrast on monitors may differ, and while a photo may look just like the rock on my end, it will sometimes appear brighter or duller on your end. I run my monitor at default brightness and contrast settings.
