Sunan Abi Dawud Book 36, Hadith 23
The Prophet (ﷺ) said: If anyone wants to put a ring of fire on one he loves, let him put a gold ring on him: if anyone wants to put a necklace of fire on one he loves, let him put a gold necklace on him, and if anyone wants to put a bracelet of fire on one he loves let him put a gold bracelet on him. Keep to silver and amuse yourselves with it.
The Prophet (ﷺ) got some ornaments presented by Negus as a gift to him. They contained a gold ring with an Abyssinian stone. The Messenger of Allah (ﷺ) turning his attention from it took it by means of a stick or his finger, then called Umamah, daughter of Abul'As and daughter of his daughter Zaynab, and said: Wear it, my dear daughter.
The Prophet (ﷺ) as saying : You women folk, have in silver something with which you adorn yourselves. I assure you that any woman of you who adorns herself with gold which she displays will be punished for it.
