Pink, obviously hoppered halite resting on a crust of small brown trona crystals. Identified on a previous dealer's label as a trona pseudomorph after halite; looks to me like a partial replacement (if any replacement at all). Same previous dealer labels has a $45 price tag. Halite has a reputation of falling apart in humid environments. However pure halite (which this is not) is quite stable (both to disintegration and color change) in a dray environment. It is the trona (frequently associated with halite from this locality) which is the culprit, so this specimen should be kept in a dry environment.
