Factum has collaborated with Sarah Sze on two-part sculptures entitled ‘Split Stone (7:34)’ and 'Split Stone (Northwest)', comprised of a natural boulder split in two like to a geode. The cut reveals a vivid image of the sky embedded into the surface of the stone.

By recording images in pixels and then fixing them in stone and pigment, Sze explores the fragility of time passing and our desire for weight and permanence in the face of both overwhelming natural forces and the ubiquitous images that surround us daily.

This work was installed at the National Roman Museum (Crypta Balbi) in Rome to coincide with Sze’s solo exhibition at the city's Gagosian Gallery (21st November 2018 - 27th January 2019) before being part of the 20 sculptures exhibited for the launch of Frieze Sculpture at Rockefeller Center, until June 28 2019.

A second Split Stone, entitled (Western) has been installed at the Western Washington University in 2019.
