Campo Del Cielo meteorite + 925 silver chain/16K gold plated chain Meteors bracelet. Each piece of jewelry is handmade with passion. Each model is unique, each stone having its own particularities and irregularities. So you don't get the same meteorite as the one pictured! 16K gold plated chain from Spain, recycled gold. Or Recycled 925 silver chain, origin Spain. The Campo Del Cielo meteorite is supplied with its certificate of authenticity, attesting to its fall 5000 years ago in Argentina in the province of Gran Chaco. It also attests to its composition (90% iron in majority, beware of allergic to niquel, it contains a little bit!) as well as its formation in the universe, probably in the asteroid belt between Mars and Jupiter 4.5 billion years ago! The stone does not oxidize, however silver may tarnish slightly depending on its use. Make a wish, meteorites have been shooting stars!
