Our Stud Earrings are mounted on a 9ct Gold tapered basket to get the flush look when worn. Many stud earrings are not done like this which means you will get an earring that may stick out too much from the ear. The post of each earring has a double notch to cater for different ear shapes and is known to give greater comfort. Carats prongs, on bigger stones, are finished the way most high quality fine jewelry is finished with slight points, signifying the work of fine craftsmen. The model wears 1.25ct. eq. stone. Also Nickel free.
