The Alais meteorite contains a number of elements in proportions similar to those of the primordial Solar System.
Notes on verification
Confirmed by Wikipedia articles on Alais and CI chondrites, plus peer-reviewed astrophysics literature (Asplund et al. 2021, Lodders 2019, Palme et al. 2022) all corroborating that CI chondrites like Alais closely match primordial solar system elemental abundances.
