How we are keeping the promise.
We’ve tested every piece multiple times in tap water, showers and swimming. Dry after contact with water. Avoid chlorine, perfume and household cleaners to help preserve the gold finish. See the specifications below for the materials and testing information we publish.

18K gold PVD over stainless steel, not brass. SGS laboratory report: nickel release below detection, cadmium and lead not detected, against European REACH limits.

Most gold jewelry at this price is brass with a wash of color over it, and nobody will tell you what is underneath. Here is ours.

Steel rather than brass. That is the part that decides whether a finish wearing thin leaves a green mark, and it is the reason the trade is worth offering. The grade is published before sale.
Laid down under vacuum rather than dipped in a plating bath. Slower, costlier, and the reason we are willing to stand behind how it wears.
Will verify by: Physical vapor deposition
Eighteen-carat gold, in a color chosen to read warm rather than brassy. How thick that layer runs is the last decision left before the first run, and the number will be published here.
Will verify by: XRF
The macro standard.
Independent reports are published here as they are completed.

Inquiry protocol
Document 4.0- Is all stainless steel the same?
- No. "Stainless steel" covers a range of alloys, and they behave differently: the cheaper ones can pit with chlorine and sweat, the better ones hold up. Ours is steel rather than a brass base, which is the difference that decides whether a worn finish leaves a green mark. The exact grade is published here rather than describe it in words that sound reassuring.
- What does PVD actually mean?
- Physical vapor deposition. It is a vacuum coating process that can produce a harder, more wear-resistant finish than electroplating, which lays a film of gold on top of the base metal in a chemical bath. Process alone does not prove durability, so the finished pieces still have to be tested.
- So how thick is the coating?
- We do not know yet, and we are not going to guess in public. Coating quotes vary enormously for this kind of finish, which is exactly why the number matters. The first batch will be measured by XRF and the reading published here, whatever it says.
- Can I shower with it?
- We’ve tested every piece multiple times in tap water, showers and swimming. Dry after contact with water. Avoid chlorine, perfume and household cleaners to help preserve the gold finish.
- Why is it more than the ten other sites selling this?
- We specify the base metal and finish, and back the pieces with our trade promise. Product pages show planned prices; the final list is published before release.
- What evidence is there for the specs?
- An SGS laboratory report from April 2026 records nickel release below detection and cadmium and lead not detected against European REACH limits.
