This interesting specimen is Anorthosite, and it is a meteorwrong or meteorite analog. It is NOT a meteorite.
Anorthosite is a terrestrial plagioclase/feldspar material that strongly
resembles pristine lunar rock - this is what virgin, unoxidized lunar
material looks like. If you search Google or Wikipedia for Anorthosite,
you will see photos of lunar materials that look exactly like the
Anorthosite offered here.
If you want to have something that looks like a lunar meteorite
fragment, at a tiny fraction of the price, this is it. This meteorwrong
is ideal for display, outreach, or educational use.
True lunar Anorthosites originate from the lighter-colored areas seen on
the Moon. These terrestrial Anorthosite samples come from deposits in Canada.
Refer to the photo. The black centimeter cube is shown for scale and is
not included. You are purchasing the large fragment shown, which weighs 282 grams.
