Francesco,

I am obviously in the minority, but I thought you wanted to keep the pallasite whole and just wanted to get rid of rust. Re-reading the email, it does seem that you may want to dissolve the iron to extract the olivines. If you want to extract the olivines, be aware that whatever acid you use will need to be very concentrated and VERY dangerous.

The risk/reward and return on investment seems hardly worth it.

Best,

Mendy Ouzillou

The very thought of it makes me cringe. The chances of getting crystals worthy of gem-stones, is slim. IMHO it would be sacrilege to destroy one of the most beautiful meteorite types, for a few gems and a little cash.

If there is rust between the olivines and iron, you will likely have to use an electrolytic process. KD Meteorites are the experts in doing this. If it is just a little bit of rust, then relish and then etch with Nital.
