The image is a ring size guide from HEY ZOE. It displays a table with ring sizes, showing the circumference in millimeters, the diameter in millimeters, and corresponding US, UK, and European sizes. The guide includes instructions to measure the diameter of your ring sample or, if no ring sample is available, to measure the circumference of the finger. It also features an illustration of a ring with the label "Inside Diameter" and a hand demonstrating how to measure the finger's circumference with a measuring tape. The HEY ZOE logo is displayed at the bottom, along with the social media icons for Facebook, Instagram, and Pinterest, and the handle @heyzoejewels.
