N2 - In a recent letter to the editor, Nemeth and Garvie (1) questioned our experimental evidence for lonsdaleite in ureilite meteorites, which we suggested formed via in situ chemical fluid/vapor deposition (2). The hexagonal form of diamond, known as lonsdaleite, was first reported in the Canyon Diablo meteorite where it likely formed from graphite via high shock pressures (3). Nemeth and Garvie previously argued that the lonsdaleite in Canyon Diablo is instead a defective diamond (4) or combined graphite/diamond complexes coined, “diaphites” (5).
