Description

Hello up for sale is NWA 11237 classified as a Lunar Feldspathic Breccia. This gorgeous fresh individual weighs 5.191 grams; it has a beautiful shape and traces of fusion crust, a very unique and desirable matrix. I have recently purchased 125 grams of this material, so there is very little available. This is one of my favorite Lunars; it definitely has an odd and exciting new look. Thanks for your interest and take care. It comes with a COA card and display case.
