Musnad Ahmad 1193:1

Waki’ narrated to us, he said: Sufyan narrated to us, from Mansur, from Rib’i, from his wife, from a sister of Hudhayfah, who said: The Messenger of Allah (may Allah bless him and grant him peace) addressed us and said: "O assembly of women, do not wear gold. Is there not for you in silver that with which you may adorn yourselves? There is no woman among you who adorns herself with gold and displays it, but she will be punished for it."
