Astraeus - Titanium Ring with Wide Meteorite Inlay

Astraeus carries the widest meteorite inlay in our CELESTIUM collection. Named after the Greek Titan of dusk and the stars, it's built around a single idea: let the meteorite speak. The band measures 6mm of polished titanium, and the genuine Muonionalusta meteorite running through it is 4mm wide. That leaves only a narrow border of titanium on each side, so most of the ring's face is meteorite. The Widmanstätten pattern becomes the whole point of the ring, not an accent to it.

What Makes Astraeus Different

Wide Genuine Meteorite Inlay

Most meteorite rings use a narrow inlay. Astraeus doesn't. At 4mm in a 6mm band, the inlay is wide, which means more of the Widmanstätten pattern is visible. This is the geometric lattice of interlocking crystals that forms as iron-nickel metal cools over millions of years in zero gravity, and it's the one thing that proves the material is real. It can't be faked, and no two pieces are identical. If you're researching meteorite rings carefully, our guide on how to tell if a meteorite ring is genuine walks through every visual and physical marker of authentic material.

Muonionalusta meteorite is distinguished by its finer, more intricate crystal structure and characteristic blue-silver sheen after acid etching. It's visually distinct from Gibeon, the other meteorite we use in the CELESTIUM collection. For a detailed comparison of both meteorites, see our meteorite science guide.

Polished Titanium Band

The meteorite sits in a polished aerospace-grade titanium band. Titanium is lighter than steel, stronger than most precious metals, and naturally hypoallergenic. It's the same material used in aircraft and surgical implants. The polished finish creates a clean contrast with the meteorite's textured surface without competing with it. Unlike tungsten, titanium has some flex under impact, which makes it a better choice if you're harder on your hands.

The 6mm Profile

At 6mm, the band sits in the middle ground. Substantial enough to carry the wide inlay and show the meteorite pattern clearly, narrow enough to wear comfortably every day. The comfort-fit interior means it slides on and off easily and doesn't dig in at the edges during extended wear.

Muonionalusta Meteorite

Muonionalusta meteorite landed in northern Sweden approximately one million years ago, making it one of the oldest confirmed meteorite finds on Earth. Its origins, however, go much further back. The material formed during the early solar system, over 4 billion years ago, in the core of a small planetary body that never fully developed.

What makes Muonionalusta distinctive among meteorites used in jewellery is its crystal structure. The Widmanstätten pattern (the geometric lattice that appears when the meteorite is cut and acid-etched) is finer and more intricate than that of Gibeon meteorite, with a characteristic blue-silver tone. This pattern formed as molten iron-nickel cooled at approximately one degree per million years in the vacuum of space. The result is something that cannot be manufactured or replicated on Earth. Every piece is unique.

The meteorite in Astraeus is finished with an electrophoretic coating applied during manufacture. Unlike brush-on wax or standard polymer sealants, e-coating is applied electrically. The protective layer is drawn uniformly across the surface for consistent coverage and stronger adhesion. It's the same principle used in automotive corrosion protection. The result is a more durable starting point than most meteorite rings on the market, designed to hold up through years of daily wear rather than occasional use.

Aerospace-Grade Titanium

Titanium was first isolated in 1825 and named after the Titans of Greek mythology. It's since become the material of choice for aerospace engineering, surgical implants, and high-performance applications where the combination of strength, low weight, and corrosion resistance matters.

For Astraeus, we use aerospace-grade titanium polished to a high lustre. It's roughly 45% lighter than steel at comparable strength, naturally hypoallergenic, and unlike tungsten it has some give under impact rather than cracking under extreme force. The polished finish ages well and holds up to daily wear without special treatment.

Titanium is biocompatible and won't react with skin. It's suitable for long-term wear even for people with metal sensitivities. Independently tested to EN 1811:2023 with nickel release below the laboratory detection limit. See our hypoallergenic rings guide for full testing detail.

Construction

The meteorite inlay is precision-cut and set flush with the titanium band. Once set, the inlay is finished with an electrophoretic coating that is applied at the manufacturing stage, not added afterwards. The result is a smooth, even surface with consistent protection across the meteorite. The meteorite sits level with the metal rather than proud of it, which protects the inlay edges and makes the ring more comfortable against adjacent fingers.

Every Astraeus ring is finished with an electrophoretic coating (e-coat) applied at the manufacturing stage. This bonds a protective layer to the meteorite at the molecular level, the same principle used in automotive corrosion protection. It's a substantially more durable seal than the brush-on wax most meteorite ring makers use, designed for years of daily wear rather than occasional use.

In practical terms: Astraeus handles incidental water contact without issue. Handwashing, getting caught in light rain, or accidental splashes won't damage the meteorite. The care guidance below is about extending the ring's appearance over decades, not preventing immediate harm.

About Titanium

The titanium base is highly corrosion-resistant and won't tarnish, rust, or react with skin. Unlike tungsten, titanium has some flex under impact and won't crack or shatter under extreme force. The polished finish will pick up fine scratches over time with daily wear, which is normal for titanium. These can be buffed out professionally or left as a natural patina of use.

If the Meteorite Develops a Patina Over Time

The e-coat is durable but not indestructible over decades of daily wear, particularly with regular exposure to water and chemicals. If you notice subtle darkening on the meteorite inlay over the years, this is a natural patina that adds character. Light patina is normal and doesn't affect the ring's integrity. If you want to reverse it, apply Renaissance Wax. In rare cases of significant oxidation, professional restoration is available through Foundoria as part of our lifetime warranty service.

Warranty note: The e-coat is covered against manufacturing defects under our lifetime warranty. Wear-related changes to the meteorite's appearance (natural patina, surface character developed over years of use) are not defects and are part of how iron-bearing material naturally ages.

Avoid: Ultrasonic cleaners, steam cleaners, abrasive polishes, and prolonged submersion in chlorinated water. These can compromise the e-coat over time.
