Looking for the hardest, unscratchable finish for jewelry
RFQ: I am looking for someone to coat metal rings to the hardest finish possible.
I would like a diamond coating, it will work well with my marketing. It can't have nickel in it. I'd like a black and a gunmetal color with polished and matte finishes. Rings would be tungsten, titanium, and damascus stainless steel.

RFQ: I have samples from a couple providers that are using different DLC processes. I am open to anything that makes sense.

Hi Wayne,
adv.
I may be able to coat by hard anodizing your titanium rings later in January. Waiting for the equipment to arrive soon. So far it is the strongest coating with bright surface. Contact me directly please.
On the image on the left - this new coating. On the right - hard anodizing 2488 without tumbling.
