I. The Metaphysical Reading
How the stone has been held.
Aragonite sputniks are traditionally held as grounding stones for those whose attention has spread thinner than the day can carry. Practitioners describe the radiating clusters as a physical model of returning to centre, energy sent outward from a stable body rather than scattered from an anxious one.

II. The Scientific Reading
What the lattice actually does.
Aragonite is the orthorhombic polymorph of calcium carbonate, less stable at surface conditions than calcite but favoured in warm seawater and in most mollusc shells and coral skeletons. On geological timescales it recrystallises to calcite, which is why fossil ammonites are usually calcitic even though they were originally aragonitic. The reddish sputnik habit famous from Molina de Aragón forms by twinning across three interpenetrating pseudohexagonal axes.
