Are "man-gagement" rings the next wedding trend?

Gay weddings aside, more and more men are opting to wear "man-gagement" rings. U.S.-based jewelry stores Blue Nile, James Allen, and Gemvara are among many retail outlets reporting a recent increase in engagement rings for men. Why now? In relationships, gender roles are more balanced than ever. And an increasing number of women are opting to propose to their boyfriends, rather than the other way around. The most popular styles for men are classic bands, some carved, an others with diamonds.
