Why our meteorite rings are popular (based on your feedback!): The perfect alternative gift for weddings (think something old!) or engagements, and they also serve well as a gift to celebrate the 11th "iron" anniversary. The "Widmanstatten pattern" on each ring is unique. (Read our blog on the history of the Muonionalusta to learn more about this special meteorite.) Estimated to be 4 billion years old we love that you can wear something literally from outer space. The accompanying certificate of authenticity provides detail on the meteorite and it's discovery location. Some common questions we get about Muonionalusta Meteorite Meteorite is predominately iron - how do you prevent rusting? Iron is highly susceptible to oxidisation (rust), to ensure it's longevity we have applied a specialized 3-micron white gold coating. This creates a protective barrier. How do we look after something so old? All our jewellery comes with a care sheet. Our top advice is NOT to get the meteorite wet and avoid applying perfumes and lotions once you are wearing the jewellery. What's included with the purchase? A certificate of provenance, a gift card with Meteorite information on, a care sheet and a silver polishing cloth.
