Colette [Sidonie Gabrielle Colette] (1873–1954), French author. Aunt Alicia, in Gigi (1944, trans.1953).
When asked (by Gilberte) "What is an artistic jewel?" Aunt Alicia replied, "It all depends. A mermaid in gold, with eyes of chrysoprase. An Egyptian scarab. A large engraved amethyst. A not very heavy bracelet said to have been chased by a master-hand. A lyre or star, mounted as a brooch. A studded tortoise. In a word, all of them frightful. Never wear baroque pearls, not even as hat-pins. Beware above all things, of family jewels!"
