My advice is to stay away from any sliced pieces with a lacquer or
clear-coat surface. It is sign that shortcuts were taken in its
preparation. Proper polishing reduces the surface area on cut pieces of
any meteorite aiding in the prevention of "lawrencite disease." Not
only that, these coatings will accelerate the deterioration process by
trapping moisture. It is important to store this material in low
humidity environments with plenty of air circulation. Also, exposure to
direct sunlight will cause the crystals to darken with time.

A lot of collectors are in the wait and see mode since there are several
metric tons of this material available. The lowest price I have seen was
around 46 cents a gram for a recently sold piece on eBay.

Happy Collecting,

Adam
