Most Gems En Vogue rings can be sized up or down two sizes (eternity bands cannot be sized).  If you want to confirm that the ring can be sized before you purchase the ring, please call Jennifer at 1-800-268-7962 or email info@gemsenvogue.com .  Once you purchase the ring, if you would like to have it sized pre-shipping, we can do that (please note sized rings cannot be returned), just call Jennifer with the purchase order number.  If you would like to receive the ring first, we will size at a future date for you.
