I have not cleaned this. The necklace is not the original one to the set, it is sterling silver but I just put the cross on it so the set had a nice heavy necklace. It is a gold washed sterling silver rope style and is pretty heavy. It kind of matches the rope edge on the Crosses. The earrings measure approx 2 3/8" long overall by 1 5/8" wide, the cross Charm Necklace is approx 2 1/4" long overall by 1 5/8" wide, and the necklace is approx 18" long. All the items are hallmarked. I do combine shipping please check out my other listings. This will be shipped in a box
