Marthe, Marguerite's neighbour, notices the jewellery and says it must be from an admirer. Marguerite tries on the jewels and is captivated by how they enhance her beauty, as she sings in the famous aria, the "Jewel Song" ("Ah! je ris de me voir si belle en ce miroir"). Méphistophélès and Faust join the women in the garden and romance them. Marguerite allows Faust to kiss her ("Laisse-moi, laisse-moi contempler ton visage"), but then asks him to go away. She sings at her window for his quick return, and Faust, listening, returns to her. Under the watchful eye and malevolent laughter of Méphistophélès, it is clear that Faust's seduction of Marguerite will be successful.
