Columbianites



To all:

Are Columbianites tektites or impactites? Apparently there's now two schools
of thought. (To those unfamiliar with these, they come from the N-W of
Columbia, S.A. and can be quite attractive, roundish to teardrop shaped,
sharing the translucence of Moldavites although they are "lilac"-colored
instead of green.)
