We introduce Nd3Sb3Mg2O14 with ideal kagome lattices of neodymium ions in ABC stacking. Thermodynamic measurements show a Curie-Weiss temperature of ΘCW = – 0.12 K, a Nd3+ spin- 12 Kramers doublet ground state, and a second-order phase transition at TN = 0.56 (2) K. Neutron scattering reveals noncoplanar scalar chiral k = 0 magnetic order with a correlation length exceeding 400 Å = 55a and an ordered moment of 1.79 (5) μB. Furthermore, this order includes a canted ferromagnetic component perpendicular to the kagome planes favored by Dzyaloshinskii-Moriya interactions.
