Santos;
Here are some Niobium earrings that were done several years ago. I have had them in stock, and not sold them. There not to fancy, just a little texturing on them. Niobium is worked like Titanium, except that you do not have to use acid in the process, and it is still a hypoallergenic metal.
The colours are very nice and it seems more easy to anodize than Ti . I know some cutlers that are using Niobium and Inox steel alloys .
I’ve to found pure Niobium and get a try with selective anodizing.
Thank you Everett,
