Northwest Africa 1817
Type B Mesosiderite
Found 2003

I did a bit of looking into the differences in Meso Types A, B, C with Dr Ted Bunch at NAU and DR. Alex Ruzicka with Cascadia Meteorite Lab The difference lies in pyroxene differences:

TYPE A plagioclase>Ca-pyroxene> orthopyroxene
TYPE B clinopyroxene>plagioclase>orthopyroxene
TYPE C abundant orthopyroxene with traces of Ca-pyroxene and plagioclase

and the implication suggests a NEAR-SURFACE ORIGIN in Type A toward A DEEPER ORIGIN FOR Type B and C (going deeper) though the differences are not yet fully studied.

NWA 1817 has a very high metal content and cutting and polishing losses came to about 50%, but I reached a point where I didn't care...I wanted these to shine...and they do.

I have always collected for quality above quantity and I wanted these beauties to glow. They are polished to rival Chinga, they reflect a 10 point font perfectly readable. Problem is the camera is having a hell of a time catching them. There are fine scratches, the result of polishing to glasslike and then having a single bit of stone pop out and scratch the metal, there had to be some stopping point.
