Make your friends and neighbors green—green with envy, that is—by sporting recycled gold (and other metals like silver and platinum) jewelry by greenKarat, a company that makes noble efforts to inform consumers of the eco-horrors of mining while offering drool-worthy baubles. The company provides a link to Green Assay where you can track the unique ecological characteristics of your bling and also gives customers the enticing options of recycling old gold jewelry for store credit, reusing it for new pieces, or donating it to benefit an environmental charity.
