Hello, Harlan and the list,
The first question, I don´t know, but do know, the first man-made
diamonds were russian origin.
The second question, the etche pattern doesn´t show, if the FeNi
has cooled faster than 1 degree Celsius in a mA or so, it´s impossible
to create those circumstanses on the earth.
Anyway, according the description, Shirokovsky metal contains 20 -
47 wt% Ni, and this is too much for the etche pattern, like in Ataxites.
By the way, please, have a look on the site;

Nice photogallery, but not a piece of a meteorite in it. Well, if I had
150 kg:s, I sure would add some pics... Also, I don´t know, if the
russian metal-detectors are water-proof, but the model in the picture
looks to me more wise to use on the ground than in the under-water
search...;-
Also an open question to me is, why they didn´t use a magnetometer
in the serach...
best rgds,
pekka

in the manufacture of steel, siliceous minerals float on the molten iron and are not mixed in because of the iron's greater density. even in a zero -gravity situation, the density differences would push the lighter materials to the surface or outside of the molten iron body UNLESS there was extreme pressure and current such as found in the mantles of planets. in the shirokovsky scheme, how would the olivene be thoroughly mixed? also, would an etche pattern show up even if the "iron matrix" in a fake was made from actual meteorite like gibeon , sikhote shrapnel etc.?
