Find Your Ring Size | Hancocks Signet Rings

For our UK customers please click here and use the contact form to request your free finger sizer in the post.

We offer one complimentary finger size adjustment with each order within a tolerance of three sizes up or down and brought to us within 28 days of collection/delivery from us.

If the ring needs adjusting by more than three sizes up or down or after the 28 days then this can be done but it will incur a charge.
