Most Selene rings are offered as paired sizes (J/K, L/M, N/O, P/Q, R/S). If you are between sizes or buying as a surprise, borrow a ring they already wear and match the inner circle to the chart, or contact us for a free ring sizer.
If a ring arrives and the size is not quite right, we offer one free resize within the first year on eligible rings. See delivery and returns.
