At this year’s Frieze Masters fair, in London’s Regent’s Park, amid booths filled with work by Brueghel, Miró, and Rauschenberg, there was also a collection of some of the oldest and most eye-catching creations in the universe: meteorites.

Studded with gem-like glass or lined with striations of crystallized metal formed as they blazed through the sky, these meteorites had been sliced open to reveal their interiors, or polished into gleaming orbs, or left in a raw sculptural state complete with a burnished fusion crust. The result was objects of astonishing beauty and sky-high price tags.
