CELESTIUM

Two meteorites. One collection.

The CELESTIUM collection features two of the most remarkable meteorites used in jewellery: Gibeon and Muonionalusta. Both are genuine space rock, both carry the Widmanstätten pattern — the crystalline structure that forms only in the vacuum of space over billions of years — but each has a distinct character, appearance, and story.

Gibeon meteorite fell to Earth in prehistoric times, landing in what is now Namibia. First documented in the 1830s, it is estimated to be over 4 billion years old — predating our solar system's planets. Its Widmanstätten pattern features bold, broader crystalline bands with warm grey tones. Gibeon is featured in our tungsten carbide rings.

Muonionalusta meteorite landed in northern Sweden approximately one million years ago, making it one of the oldest known meteorite finds on Earth. Its Widmanstätten pattern is finer and more intricate than Gibeon's, with a distinctive blue-silver sheen after acid etching. Muonionalusta is featured in our titanium rings.

What makes meteorite rings unique?

The Widmanstätten pattern in each meteorite fragment formed as the rock cooled at an extraordinarily slow rate — approximately 1°C per million years — in the vacuum of space. This process cannot be replicated artificially. It means the pattern on your ring is genuinely one-of-a-kind: a cosmic fingerprint that no other ring in existence shares.

Why choose a meteorite ring?

Truly unique: Every meteorite fragment displays a different Widmanstätten pattern. Your ring is unlike any other ring ever made.
Ancient history: Gibeon is over 4 billion years old. Muonionalusta arrived on Earth a million years ago. No gemstone or precious metal comes close to this history.
Symbolic meaning: For those drawn to astronomy, science, or the idea that their love is written in the stars, a meteorite ring carries genuine significance.
Natural variation: Each ring features real meteorite — not a print or reproduction. Dark spots (troilite inclusions), subtle rust tones, and pattern density variation are natural properties of the material, not imperfections.

Natural variation — what to expect

Because meteorite is a natural material, no two rings are identical. Variation between pieces is normal and expected, and includes: differences in Widmanstätten pattern density and band width; subtle colour variation from warm grey to cooler silver tones; dark spots or flecks caused by troilite or other mineral inclusions; occasional micro-pitting from the meteorite's journey through the atmosphere; and faint rust tones where iron content is higher. These are not defects — they are evidence of authenticity. A meteorite ring without natural variation would not be a real meteorite ring.

How we protect your meteorite ring

Raw meteorite contains iron, which can oxidise with sustained moisture exposure. All CELESTIUM rings set the meteorite as an inlay within tungsten carbide or titanium — the meteorite is sealed to prevent water contact while preserving its striking visual appearance. With reasonable care, your ring will maintain its character for decades.

The Foundoria difference

Every Foundoria ring is independently lab-tested to meet REACH and GPSR safety standards, ensuring our rings are hypoallergenic and safe for the vast majority of skin types. A complimentary ENDURA silicone companion band is included with every order — for the gym, manual work, or anywhere a metal ring isn't appropriate. A free ring sizer is available on request before you order.

FAQs

Yes. CELESTIUM rings feature genuine Gibeon and Muonionalusta meteorite. Gibeon is one of the most well-documented meteorites used in jewellery, prized for its bold Widmanstätten pattern and stability. Muonionalusta is sourced from northern Sweden and is notable for its finer, more intricate crystalline structure and blue-silver sheen. Both are authenticated meteorite material.

Gibeon is over 4 billion years old and fell in Namibia. It has broader, bolder Widmanstätten bands and warm grey tones — it features in our tungsten carbide rings. Muonionalusta is approximately one million years old and landed in Sweden. Its pattern is finer and more intricate, with a distinctive blue-silver sheen after etching — it features in our titanium rings. Both are genuine meteorite; the difference is character and origin.

Because every piece of meteorite is unique. The Widmanstätten pattern, colour, and surface detail vary naturally between fragments. Dark spots (troilite inclusions), subtle rust tones, pattern density variation, and micro-pitting are all normal properties of real meteorite — not defects. Product photography shows one specific ring; your ring will have its own pattern.

Meteorite contains iron, which can oxidise with prolonged moisture exposure. The meteorite inlay in CELESTIUM rings is set within tungsten carbide or titanium and sealed to prevent water contact. With normal care — removing your ring before swimming or prolonged water exposure and drying promptly after hand washing — your ring will maintain its appearance for years.

Remove your ring before swimming, showering, or using cleaning chemicals. If your ring gets wet, dry it promptly with a soft cloth. For cleaning, use a slightly damp cloth and dry immediately. Avoid ultrasonic cleaners or harsh chemicals. Store in a dry place when not wearing.

Tungsten carbide and titanium rings cannot be resized after manufacture. If you are unsure of your size, a free ring sizer is available on request before you order. If you're between sizes, go half a size down — our comfort-fit profile wears slightly larger than a flat-fit ring of the same nominal size. Free size exchanges are available if the first size isn't right.

Yes. Gibeon and Muonionalusta meteorite are primarily iron-nickel alloys — materials commonly used in jewellery. Both pose no radiation risk and are safe for everyday wear. All Foundoria rings are independently tested to REACH and GPSR safety standards and are hypoallergenic for the vast majority of wearers.

The Widmanstätten pattern in both Gibeon and Muonionalusta formed over billions of years as the meteorite cooled in space at approximately 1°C per million years. Because this process is entirely natural, every fragment displays a unique crystalline structure. No two meteorite rings — from any brand, anywhere in the world — will ever share the same pattern.

I bought the Strung-Coffee Tungsten with Guitar String ring from Foundoria as a tribute to my father-in-law, a man who spent most of his life with a musical instrument in his hands and, I suspect, a tune permanently stuck in his head. If there was a guitar within a 50-mile radius, he would find it, tune it, and probably improve the evening for everyone in the room.

So when I saw a ring with an actual guitar string running through it, it felt less like buying jewellery and more like buying a tiny wearable concert.

The ring itself is fantastic. The tungsten has that reassuring “I could probably survive a small meteor strike” weight to it, and the coffee-coloured finish gives it a classy look without screaming “rock star trying too hard.” Then there’s the guitar string inside, which is such a brilliant touch that every time I look at it I half expect it to start playing a blues riff.

It’s subtle enough that most people don’t notice it at first… and then when they do, they lean in closer like they’ve discovered some secret Easter egg.

But the best part is the meaning behind it. Wearing it feels like carrying a little reminder of my father-in-law’s lifelong soundtrack — the countless songs, late-night strumming sessions, and the general belief that life is better when someone picks up a guitar.

In short:
Beautifully made, unique, and meaningful.

If you’re looking for a ring that combines craftsmanship, originality, and just a hint of rock-and-roll soul, this one absolutely hits the right note.

Five stars. No tuning required.

I recently bought the Aurin-Black Tungsten Ring with Rose Gold and I must say, it’s dangerously good-looking.

The ring itself is absolutely beautiful — the black tungsten with the rose gold detail looks fantastic. It fits perfectly too, which is impressive considering my previous attempt at measuring my finger involved a bit of string, a ruler, and a strong sense of optimism.

Customer service was spot on — quick, friendly, and actually helpful (which in today’s world almost deserves a medal).

The only downside is that I now seem to spend a surprising amount of time admiring my own hand like a Victorian aristocrat who’s just discovered jewellery. If you catch me casually resting my hand on tables so the ring is visible… no you didn’t.

All in all, I’m absolutely chuffed with it. Lovely ring, great service, and I’d happily recommend Foundoris to anyone looking for something that makes their hand look significantly more sophisticated than the rest of them.

Thanks very much!

Great look, good material. Looking forward to wearing it permanently.

My Boyfriend absolutely loves this ring. It is so personal to him, his favourite colour being purple and his love of space. Splendidly crafted. Looks divine. And what beautiful quality packaging!
