This Olivine-rich Lherzolite, known as a ‘volcanic bomb’ as the olivine is formed deep in the earth’s mantle, and is pushed up via volcanic action- this piece (along with its other half) was expelled during a volcanic eruption in the Almadinah Volcanic complex in Saudi Arabia long ago. It rained back down to earth and hardened into a crust covered nodule, which was eventually retrieved from the desert in modern times and cut to reveal the crystals within

Created by artist Lee Downey, known for his carvings of skulls from many natural materials, and items such as pool / billiard balls. This skull is hand carved from a duck pin bowling ball with immaculate detail. Wonderful on its own, with crisp lines and stirring red & gold swirls from the bowling ball medium, it's a conversation piece for sure.

Does any one recognize this vert, or have any ideas?
