This is another attempt at focus stacking. I used four bright hot bare bulbs for light, which means the highlights are all blown out. As before, this isn't as sharp as I'd like. This specimen was collected from Dish Hill, which is a volcano in Southern California just off of Route 66 east of Barstow. The yellow green crystals are peridot, the dark green crystals are fayalite and the black mineral is pyroxene. This is a xenolith (which means it originated in the Earth's mantle and was ejected up to the surface during a volcanic eruption).
