The gentle texture of these hammered post earrings reminds me of seeing rain falling on a pond. The upper surface is semi-matte, while the recessed hammer marks are shiny, which helps create this illusion. These earrings are petite and excellent for everyday wear. 100% sterling silver with 925 stamped on the ear posts. The circles are slightly less than .25 of an inch across, or 6 mm exactly. These earrings will be shipped gift-wrapped. Please see my profile for more information about my jewelry and my shop policies.
