After getting married, if one disenchants their wedding ring 'The Bond of Matrimony',  you receive the enchantment, 'Blessing of Mara.' Disenchanting has no effect upon your marriage.

The base effect of this enchanment is that Restoration spells cost 10% less, but it does increase as your character levels up.

This enchantment is different than Fortify Restoration, and cannot be equipped onto any item, i.e., shields, gauntlets, helmets, armor, rings, necklaces, or clothes.
