Two pavé wings meet at the centre, set wide across the collarbone, and from that point a cushion-halo pendant drops free. The structure is in two parts that belong to each other — the spread of the wings above, the weight of the stone below. A 1.0 ct round brilliant, 6.5 mm across. The refractive index of moissanite is 2.65. All of it moves when she moves.

Lab-grown today using the same chemical structure — silicon carbide — with a refractive index higher than diamond. 9.25 on the Mohs scale. It doesn't scratch, cloud, or fade. Independently Certified Every Luhusati stone comes with a GRA certificate of authenticity. D color, VVS1 clarity — the same grading language used for diamonds, applied to a stone that earned it. Passes the Diamond Test Moissanite conducts heat at near-diamond levels. The tester can't tell the difference.
