The Cassiopeia is a Muonionalusta meteorite ring set in sterling silver with tellurium copper accents. Muonionalusta is a rare iron-nickel meteorite recovered near the village of Muonio in northern Sweden — formed over 4 billion years in space and prized for the broad Widmanstätten crystalline pattern it reveals when etched, a structure that cannot form on Earth and cannot be faked. Each ring is cut from a genuine slice of this meteorite, so every Cassiopeia carries a one-of-a-kind pattern that existed before our planet did.

The design frames the cosmic iron between bright sterling silver edges, with a warm pinstripe of tellurium copper for contrast — a mixed-metal composition that reads formal enough for a wedding band and distinctive enough for a signature piece. A protective finish over the meteorite section guards the iron against moisture in daily wear.

Muonionalusta is a rare iron-nickel meteorite found near the village of Muonio in northern Sweden. It formed over 4 billion years in space and is prized for its broad Widmanstätten crystalline pattern — a natural structure that cannot be replicated on Earth.
Yes. Each ring is cut from genuine meteorite, and the Widmanstätten pattern differs in every slice — no two rings are identical. The band pairs the meteorite with sterling silver and a tellurium copper accent.
The Cassiopeia is available in 6mm, 8mm, 9mm, and 10mm widths, in US sizes 8 through 12 including half sizes. Message us if you need a width and size combination you don't see listed.
Wipe it dry after any contact with water, keep it away from chlorine, and store it in a dry place. Sterling silver can be brightened with a silver polishing cloth; the meteorite section just needs to be kept dry to avoid patina.
