Amulet of Mara

 is an enchanted amulet, used to unlock different dialogs with some NPCs, allowing the option of marriage with them. The Amulet of Mara is purchased for 200 gold coins from Maramal. At first he can be found in the Bee and Barb, an inn of Riften town, and later in a Riften's Temple Of Mara. The amulet is also a random spawn as dungeon loot. The chest at the beginning of the Bleak Falls Barrow can produce it. The wearer gains 10% decreased spell cost for Restoration spells while wearing it. The amulet can also be found on the Stormcloak General during the defense of Whiterun. Yet another amulet can be found in a tent along the coast northeast of Dawnstar.

Other Amulets of Mara
NPCs can also possess items named "Amulet of Mara", that are enchanted. Looting and wearing the enchanted versions of the Amulet of Mara found on NPCs does not function like a regular Amulet of Mara, and will not provide the extra speech options that lead to marriage. Having these enchanted versions prevents the Maramal from selling the one needed for marriage.
