The Messenger of Allah ﷺ went out for the Eid al-Fitr prayer and did not pray any prayer before it or after it. Then he approached the women, accompanied by Bilal, and began saying, "Give in charity." So the women started tossing forward their earrings and their beaded necklaces.
حدثنا بهز حدثنا شعبة قال أخبرني عدي بن ثابت قال سمعت سعيد بن جبير يحدث

Its chain of transmission is sahih. See 1902, 1983, 2169. Sikhab, with a kasrah on the sin and a lightly pronounced kha, is a string on which beads are threaded and worn by young boys and girls. It has also been said that it is a necklace made from cloves, jalab, and musk, or similar materials, containing no gemstones or pearls at all. So said Ibn Athir.
