Help with ID please

Hi, can someone identify these rocks? They’re very heavy for their size. The large one weighing 112g and the smaller one 41g.
First found in Crane County, Tx and the second in Upton County, Tx. These are the only two that I’ve ever found.

Welcome to the site jhernandez. The stemmed piece looks to be an artifact. If it is it probably was a knife. A bit hard to tell by your pictures. But that is the only thing that looks like it may be NA to me. Kim

I wonder if it has some copper content given the green coloration. Its is way too thick for a stem.
