1 inch approx length Half inch approximate width at base of bottom part Base of top stud, approx .15” Can’t be worn as a longer Erie or as a stud these are called front/back earrings and they are absolutely beautiful. They are an antique silver metal with a genuine stone of some sorts on the inside. Now, I don’t know which one it is but it does look very similar to a turquoise. Genuine is all it has on it. Very comfortable, appropriate any occasion. Ask questions, if needed as sales final.
