Wear the cosmos.

No — and that's the point. Every Stardust piece holds a one-of-one meteorite fragment. The Widmanstätten pattern, the olivine inclusions, the crystal structure — none of these exist twice in the universe. Photos show the type and craftsmanship. The fragment you receive will be uniquely yours.

Five primary materials: 925 sterling silver (the classic choice — warm, traditional, ages beautifully), tungsten carbide (the most scratch-resistant material we work with — perfect for daily-wear rings), titanium (lightweight, hypoallergenic, excellent for sensitive skin), carbon fiber (modern, ultralight, contemporary look), and gold-plated silver (warm tone over a sterling base — luxurious without the gold-bar price). Each material is listed on every product page.

Yes — every fragment in our jewelry is genuine meteorite, hand-sourced and verified. Every piece ships with a Certificate of Authenticity issued by us, backed by our membership in the International Meteorite Collectors Association (IMCA #4748). Our certificates list the meteorite name, its origin, and the type of stone — and they are recognized internationally as professional provenance.

It depends on the material. Tungsten and titanium are virtually scratch-proof and corrosion-proof. Carbon fiber is resistant to scratches and won't tarnish. Sterling silver can develop a natural patina over years; we coat all silver pieces with a protective layer at the workshop. The meteorite itself is sealed before setting, so it stays stable through normal wear. Avoid swimming pools, saunas, and harsh chemicals — that's true of any fine jewelry.

We list every ring in US sizing on the product page. If you're more familiar with EU or UK sizes, write to us — we'll send you the conversion. If you don't know your size at all, we can also send a free paper ring sizer by post anywhere in Europe. Most rings can be re-sized once at no charge within 60 days of delivery; tungsten rings cannot be re-sized due to the material's hardness, so we recommend confirming your size first.
