This is a PSI Southwest Mesa pen in antique pewter. The blank is a PSI Penn Stone turquoise with black veins. The blank turned out okay, but it's nothing special. It doesn't look any better than the acrylic version. I doubt if I'll buy another Penn Stone blank. It was hard to work, and not worth the extra effort. I finished and polished it with 220-600 wet; all 9 grades of Micro Mesh wet; Meguiar's 105, 205, and #9.
