Description

You are bidding on an exceptional specimen of both these type locality minerals. Normally kayrobertsonite is found as matted white needles. Here a very nice spray sits up in a vug with many very sharp colorless mangangordonite crystals. Other vugs host matted kayrobertsonite and mangangordonite as well. I can count over 30 mangangordonite crystals on this piece! Holotype materal for kayrobertsonite and from my personal Foote Mine collection.
