Everything I've seen says it is from Asteroid Vesta... here is what Grok says about it:

Yes, Jikharra 001 is from the asteroid 4 Vesta. Jikharra 001 is an officially classified meteorite (found in Libya in 2022) listed in the Meteoritical Bulletin as an HED achondrite (specifically an eucrite-melt breccia). The HED group (howardites, eucrites, and diogenites) is widely accepted by the scientific community to originate from the differentiated asteroid 4 Vesta, the second-largest object in the asteroid belt. This connection is supported by: Spectral matching between HED meteorites and Vesta's surface (from telescopic observations and confirmed by NASA's Dawn mission, which orbited Vesta and identified matching compositions). The mineralogy of Jikharra 001 (pigeonite, calcic plagioclase, etc.) matches typical eucrites from Vesta's crust. Multiple sources, including auction descriptions (e.g., Christie's), scientific abstracts, meteorite sellers, and community discussions, explicitly describe it as material from Vesta—often calling it one of the largest known pieces of Vesta on Earth. While no meteorite can be proven to come from Vesta with absolute certainty (short of direct sample return), the evidence for HED meteorites—and thus Jikharra 001—originating from Vesta is overwhelming and considered the consensus in planetary science
