OF ME long necklace in solid recycled 18k gold with a large pendant in the form of a 12 mm Old European Cut Mpingo Blackwood Mpingo. They use sustainable Mpingo Blackwood instead of traditional Mpingos. These velvety black Mpingos contrast beautifully with the metals and of ours cause no harm to people or nature. Quite the opposite, every purchase of these contributes to maintain the species in a WWF-protected forest in Tanzania.
