    I’m Emory Walker. I started with Celtic rings. Not mass-produced molds, but hand-carved pieces built to last. Over time, I began noticing something strange people cared more about how metal looked than what it was. Reactions, durability, even symbolism these were afterthoughts. And I couldn’t let that go.

    This site was built for the curious, the allergic, the cautious, and the fascinated. You’ll find stories here, sure, but also science. You’ll see comparisons, not endorsements. Because I’ve worked with nearly every common metal in the craft, I know what to recommend and what to avoid.
