Astraeus Titanium Ring with 4mm Meteorite Inlay

Astraeus, the Greek god of the dusk stars, lends his name to our purest meteorite setting: a 4mm band of solid Muonionalusta meteorite set in polished titanium. The Muonionalusta fell near what is now the Swedish-Finnish border around a million years ago.

A professional electrophoretic coating protects the iron, and the titanium keeps the whole ring at a typical 5 to 8 grams.

• Band: polished titanium. Strong, hypoallergenic and noticeably lighter than tungsten.
• Inlay: solid Muonionalusta meteorite, 4mm wide, with a professional electrophoretic coating.
• Width 6mm · comfort-fit interior · typically 5–8g depending on size · sizes UK P½–Y (US 8–12).
• Made to order sizes: any size not held in stock is made for you from scratch. Made to order rings are typically dispatched in 8 to 10 weeks. Payment is taken when you order.
• REACH & GPSR certified and independently tested, so it's safe for most people.
• This ring cannot be resized, so if you're not sure of your size, request a free ring sizer first. If the fit isn't right, we offer free size exchanges within 30 days.
• Each ring is presented in Foundoria's signature eco-luxury packaging.

That's exactly what your free ENDURA silicone band is for. Wipe weekly with a soft dry cloth. See the full Ring Care Guide for more.

Will the meteorite rust?

Genuine meteorite contains iron-nickel and can develop a natural patina if left damp. Keep it dry and wipe it promptly after any moisture, and it will keep its character for decades.

Is each ring unique?

Yes. Natural meteorite varies in colour, texture and pattern, so no two rings are identical. Yours is one of a kind.

What's included in the box?

Your ring arrives in our eco-luxury clamshell gift box with a free ENDURA silicone band (£25 value) for the gym, work and travel.
