Bar mitzah gifts may include money, a gift card, Judaica items, Jewish jewelry and a charitable donation to an organization the boy supports. A guest can ask the parent or child for gift ideas, so he can find a gift that fits the boy's interests.
Money, in the form of a check, is a traditional bar mitzvah gift. It works well if the guest doesn't know what the boy wants. The number 18 is considered lucky by the Jewish people, so amounts given are frequently in multiples of 18.
A gift card works well if the guest doesn't want to give money, but also doesn't know what the boy wants. Store ideas include iTunes, Amazon.com, Starbucks, GameStop and Forever 21, as of June 2015.
Judaica items include Sabbath candlesticks, a shofar and a Hanukkah menorah. These gifts can last throughout the boy's life.
Jewish star cuff links are one example of Jewish jewelry. Jewelry can hold special significance for the boy, and become a family heirloom.
Charity is a core tenet of Judaism. A charitable donation as a bar mitzvah gift incorporates the idea of helping those in need. A donation to an organization that the boy supports, or one that matches his interests, adds a personal touch to the gift. Jewish charitable organizations are another option.
