Re: [meteorite-list] Looking for Large Slice

2018-08-27 Thread Ruben Garcia via Meteorite-list
Hi Connor,

With cutting and preparation costs nowadays your not gonna get much for a
couple hundred dollars.  Honestly, cutting a chondrite, sanding it,
polishing it would probably cost a couple hundred dollars just for simple
preparation.

Pallasites in irons could cost much more because of the etching process not
to mention Opticon and other factors.

But good luck...
