Summarize this article:

Jewish jewelry is a common gift for bar or bat mitzvahs. You can find pieces with "chai" or the Jewish star on it, and you can search in your price range. There are several websites that specialize in Jewish gifts, so you can search around to find a gift that you think the recipient would love. Just keep in mind that they will be receiving a lot of stuff at their party, so don't bombard them with trinkets just for the sake of it! Find something you truly think they'd like, or opt for money instead. Many times, friends of different faiths may not feel comfortable giving a Jewish gift, simply because they're unfamiliar with the traditions and customs. Your gift doesn't have to be faith-related at all. A nice necklace or customized photo book work just as well. A gift card to purchase a video game may be a fun gift, but something related to academics may be more practical for their future. Many times guests will contribute money for a college fund or other academic endeavor. You can also give money or items that can be used for travel, which makes for an invaluable learning experience for the child.Other things like stocks can help kids learn about the market, and so on. It may not seem normal to give a child an ultra-practical gift or money for far-off college tuition bills. However, the bar or bat mitzvah celebration is the child's ultimate gift after months, or even years] of preparation. They are the center of attention amongst all their friends and family, and your support is a present in itself. This Jewish tradition marks the beginning of the bar or bat mitzvah's adult life, and money and practical gifts are ways to start them off on the right foot.

Summary:
Give a Jewish-themed gift. Consider giving a practical gift. Remember that the party is the real gift for the child, as is the experience.
