It's the tiniest of buttons! These earrings each feature two little stamped circles in the middle of a larger circle. The circles, posts, and clutches are all sterling silver, with 925 stamped on the post. Sleek and simple, these are perfect for everyday wear. These earrings are approx. 1/4th of an inch across, or exactly 6 mm. This listing is for the bright finish but they are also available in semi-matte or oxidized upon request. These earrings will arrive gift packaged in a little box. Please see my profile and store policies pages for more information about myself and my jewelry.
