Giving jewelry as a gift—or you know, a token of undying love—is usually thought of as a guy's job. But who buys a ring, necklace or watch without knowing his partner's preferences? No one you want to grow old with, that's who.
If you want to be green, make eco-conscious jewelry your preference. And no, that doesn't mean you'll have to settle for a hemp engagement ring. If you want bling, do some homework to find conflict-free diamonds that come from mining ethically and with minimal environmental damage. Otherwise, your sparkly jewels may have origins of ecological devastation, violence and human rights violations.
If you don't want to worry about where new jewelry comes from, consider jewelry made of recycled gold and platinum or vintage jewelry. (The latter is also a good way to make sure no one else is rocking your ring.) You might also be interested in buying manmade gems that have less of an environmental or financial impact, but look just as beautiful as the real thing.
