Yellow orange colored Karibibite partly coats silvery Lollingite. Both species are generally massive but there are numerous flat surfaces on the Lollingite some of which appear to be crystal faces. The Karibite is a weathering byproduct of the Lollingite.

Condition: Fairly Good

Flaws: There are a number of bruised areas which are apparent in the pictures.
