Teen abstinance (or the lack thereof) has been fodder for a bit of national conversation lately. Most recently, there was a little dust-up at the MTV Video Music Awards about the Jonas Brothers’ proudly displayed “purity rings” (they talk about them in a YouTube video).

The rings signify the pop-star siblings’ goal to remain chaste until they are married. American Idol winner Jordin Sparks defended the J. Bros from a comedian’s attack (as did Britney Spears, but we’re not sure her vote is all that helpful). Sparks says she, too, wears a purity ring that her parents gave her.

Joe Jonas, 18, has a silver one with a cross. Fifteen-year-old Nick had his made at Disney World. And Kevin, 20, sports a punk-rock Tiffany ring covered with studs.

Want one for yourself (or your teen?).

Go straight to the source at Purity Rings and choose from a wide assortment for guys and girls. You can get a protected heart for a girl: the simple silver with a yellow diamond is $75, or the upscale diamond-encrusted one is $350 (pictured). A guy’s “One Life, One Love” runs from $40 to $350.  True Love Waits is a popular line, or you can shop at Generations of Virtue, Jewelry 4 Christians (they have a wristband, too), Factory 79 or Cornerstone Jewelry Designs.
