Jerry Travers: Tell me something -- do you still have that awful weakness for diamond bracelets?

Aunt Alicia: Without knowledge of jewelry, my dear Gigi, a woman is lost.

Lorelei Lee: I always say a kiss on the hand might feel very good, but a diamond tiara lasts forever.

Aunt Alicia: Love, my dear Gigi, is a thing of beauty like a work of art, and like a work of art it is created by artists. The greater the artist the greater the art. And what makes an artist?
Gigi: Cigars and jewelry?
Aunt Alicia: Gigi, you're from another planet.

Gigi: A necklace is love! A ring is love! / A rock from some obnoxious little king is love! / A sapphire with a star is love! / An ugly black cigar is love! / Everything you are is love! You would think it would embarrass / All the people here in Paris / To be thinking every minute of love!

Sugar: Real diamonds! They must be worth their weight in gold!

Joe: Jerry, Jerry, will you take my advice? Forget about the whole thing, will ya? Just keep telling yourself: you're a boy, you're a boy.
Jerry: I'm a boy.
Joe: That's the boy.
Jerry: I'm a boy. I'm a boy. I wish I were dead. I'm a boy. Boy, oh boy, am I a boy. Now, what am I gonna do about my engagement present?
Joe: What engagement present?
Jerry: Osgood gave me a bracelet.
Joe: [takes it and inspects the stones with Beinstock's glasses] Hey, these are real diamonds!
Jerry: Of course they're real! What do you think? My fiance is a bum?

Lorelei Lee: But square cut or pear shape these rocks don't lose their shape... Diamonds are a girl's best friend!

Aunt Alicia: Without knowledge of jewelery, my dear Gigi, a woman is lost.
