I'm giving away one Edge of Ember ring to a lucky reader! To enter, you need to be signed up for EcoCult's newsletter (to the right of this page) and Edge of Ember's newsletter (at the bottom of Edge of Ember's website). Then comment below to tell me you've done that, and you're entered! (Ends Sunday at midnight.) I've been following Edge of Ember almost since its 2013 launch. The geometric, contemporary jewelry designs caught my eye, and the fact that the collection is ethically produced in Fair Trade workshops in developing communities – Bali, Indonesia, and Phnom Penh, Cambodia – makes it one of my favorite jewelry lines. Check it out: Ten percent of profits are donated to selected charities that support disadvantaged women in the communities Edge of Ember works in. Right now, they are supporting Riverkids, a nonprofit that rescues trafficked and abused women and children in Cambodia. The pieces made in the Cambodian workshop are from recycled brass from old bombshells. The pearls are Swarovski pearls, and the lapis stones are sourced locally by their Indonesian supplier. Founder Lynette Ong grew up in Singapore, went to college at Dartmouth, worked in New York then Hong Kong, and now travels between London and Singapore. While living in Asia and working in finance, she discovered unique works of art and craft on her many travels there. She wanted to showcase the luxury craftsmanship present in Asia, as opposed to sweatshop labor we typically associate with China and Bangladesh, so she started collaborating with fair trade groups in Cambodia and Indonesia to produce her creative designs. EOE is now based in London, so the website is the best place to purchase. Delivery is free above £100 and a flat £5 charge for orders below £100.
