The Lake takes in atmospheric carbon and solar energy (but also seemingly its own heat energy) to make water, and also to make diamonds.
Neither of these processes has been directly observed owing to the impossibility of adding any probe matter to the Lake that keeps its form. Models and external studies suggest that this involves a more advanced technology than any that is publicly known. It may have mutated or evolved to that state. Nonetheless, despite its great heat and steam, the Lake’s water level is constant.
The Lake also makes a kelp-like formation of long, grassy diamondene fronds, that decay in days to a non-diamond crystal known as “carbon sand”. The fronds float on the surface of the White Lake, giving it its eponymous color. They are diamagnetic, repelling magnetic fields. At night, perhaps because they can’t collect solar energy, the fronds sink too low for the diamagnetic effects to support a magnetic object.
The movements of the Lakeskin and the boiling-hot water push diamonds toward the shore, along with carbon sand, the granular remains of old Lakeskin. Most mornings large raw diamonds can be found on shores.
The prospector István engineered electromagnetic boots that let the wearer skate above the Lake, creating what is now a hugely lucrative extreme-sports franchise. This has dramatically added to the value of the Lake.
