Sterling silver stud earrings set with diamond. These earrings have two pieces. The first is just the plain stud but you can add the bottom section and have the stud and a little diamond sitting at the bottom of your ear lobe. Stones test in diamond range on my presidium gem tester but I do not know if they stones are natural or lab-created. Earrings measure in their top with bottom form, approx. 9/16ths of an inch length and 5mm across widest point. There are tiny stamps which can be seen through a loupe on the bottom half of the earrings that say S925, D 1.00ct, and earrings acid test positive for sterling silver. O
