Subject: Re: [meteorite-list] Stability of Sericho (Habaswein)
The fact that dealers are applying sealants and anti-rust coatings to this
Pallasite, like an old 55 Chevy from the East Coast, indicates that
Sericho (Habaswein) is indeed a ruster. I received several reports today
of rusticles, green goo, chemical smells, dislodged crystals and popping
noises coming from specimens. Maybe it should be upgraded from ruster to
serious ruster.
Stable Pallasites like Esquel do not require any special treatment other
than avoiding chlorinated water during preparation, proper high-grade
polishing and low humidity storage/display.
I avoid rusters at all costs,
Adam

I got my sealed full slice of Habaswein from Rob many months ago and
don't see a lick of rusting on it. Sealant appears to be working great.
:-D
If I were in the market for a specimen, I'd listen to the guy who
actually has experience working with the meteorite in question.
Additionally,
Large multi-kg specimens of Habaswein do sell in the 0.5$/g range.
Expertly prepared slices do not. They sell for 8-10 times that price.
That distinction needs to be made.

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

Hello Dear List Members,
Just a small question to new Sericho (was Habaswein) Kenya pallasite
owners, dealers, cutters: how stable is it?
From my own experience I noticed its extreme degree of instability,
similar to Admire or even more... Is this unlucky piece, just fortuity
or is it really so?
Thanks in advance for your answers,
Andrey,
