Over roughly the last decade, a visible, community-led Diamond Open Access (OA) ecosystem has emerged in the Earth sciences, not as a departure from tradition, but as the latest expression of a long-standing culture of open, society-supported scholarly communication. While free-to-read, fee-free publishing initiatives have deep roots in the field, predating the Diamond terminology by decades and encompassing regional infrastructures and institutional serial publishing by geological surveys and learned societies, the period since the mid-2010s has brought a new wave of explicitly Diamond-identified, community-governed disciplinary journals that have transformed the visibility and ambition of this model. This article analyzes that transition through a field-specific lens, taking journals such as Volcanica, Seismica, Tektonika, Geomorphica, Geodynamica, Sedimentologika, Advances in Geochemistry and Cosmochemistry, Open Paleontology, Planetary Research, and Journal of Studies of Earth’s Deep Interior as emblematic of a broader shift in scholarly communication. Building on current Diamond OA debates, we argue that Earth sciences Diamond journals are not merely “no-fee” outlets but sociotechnical experiments in reclaiming agency, redistributing publishing labor, and redefining value away from commercial metrics. This article develops three claims. First, the Earth sciences Diamond turn has been enabled by existing community infrastructures and high levels of volunteer coordination, but it remains uneven and fragile. Second, Diamond models strengthen equity for authors and readers while exposing unresolved tensions around labor sustainability, institutional support, and recognition regimes still structured by prestige metrics. Third, Earth sciences offer a strategically important testbed for a wider transition towards commons-based scholarly communication, especially where global fieldwork, data justice, and decolonizing commitments demand alternatives to the pay-to-read and pay-to-publish systems. We conclude that the next decade should prioritize durable funding compacts, shared technical infrastructure, and reform of research assessment so that Diamond OA can scale without reproducing extractive or technocratic governance.
