While demonstrating standards of quality and excellence, World of Diamonds has been behind it all. A Spirit of Ecstasy, the bonnet ornament on Rolls-Royce automobiles, encrusted with 2851 diamonds weighing 38.80 carats and handmade in solid gold that costs more than the car itself. A jewelry collection inspired by the city of Geneva. Diamonds cut in the shape of a crescent moon, because in Roman Catholic Marian veneration, it is associated with the Virgin Mary.
