Lot Essay

Less than 0.2% of all meteorites are pallasites, the most beautiful extraterrestrial substance known. Pallasites are formed at the core-mantle boundary of an asteroid that underwent a mixing of the core’s molten metal with stony olivine from the mantle. The result of olivine crystals suspended in an iron-nickel matrix is enchanting. As seen in this sphere, Seymchan also contains gem-quality olivine otherwise known as peridot (the birthstone of August). Recovered in Siberia, this wondrous three-dimensional presentation reveals aspects that are impossible to see on a flat surface. It appears the olivine is suspended or floating in a metallic sea—an image not far afield from the actual case of its parent asteroid adrift in the void of interplanetary space. Originating from a larger Seymchan mass, this machined sphere underwent a number of stages of grinding and polishing in a sphere-making apparatus in what is truly an alluring extraterrestrial crystal ball.
