Rings are available in the sizes shown in the description at no extra charge. If you need a different size than what is shown, there is an extra charge of $25.00 and this can take up to 2 weeks. We can size full sizes, quarter sizes and half sizes up or down. Some of the thicker mens rings can only be size up or down one size. Please email us to inquire about this at firstname.lastname@example.org if this is an issue.
