I have always loved the weight and patina of platinum and always choose this for my ring projects. I recently had a ring made in Sweden and they weren’t originally willing to make the ring in Platinum/Ruthenium as Cobalt seems to be the alloy of choice. After finally finding someone to cast the ring in England in PT950/RU, I was able to get the ring engraving/miligrain work done in Sweden and was very happy with the results. Any of my PT950/RU rings that I have had made with engraving and miligrain have never shown any signs of wear over the years. I know PT900 & Iridium is also a comparable choice but I don’t think it is a recognized hallmark in Europe but I could be wrong (?) Anyways, I am currently working on a few more rings and planned on using PT950/RU again for these. They will actually be casting them in a 3D printer and I don’t know much about the process but can’t wait to see some pic’s of it when it is complete. They asked me if I would be interested in using a new platinum/iridium/gold product but I didn’t think I wanted to chance it on these particular rings. From reading about it, it looks like a very hard wearing material. Was curious if anyone has heard about this or used it yet in fine jewelry? Does anyone know how this will be hallmarked?

Here is the company info I was sent to read about it:

No idea but it sounds amazing and looks gorgeous. Please let us know if you go ahead with it for anything
 
I would bet that the "new" alloy is to offer a nickel free white gold. Right now, most nickel-free white gold uses palladium and gold. This seems to just replace the palladium with platinum+iridium. Is should be fine, as long as you are happy with the metal color. Platinum, iridium, ruthenium and palladium are all in the same family of metals. I would guess they are using a powdered metal material and a laser vs. an extruded material as is used in home-machines. They should work from a CAD model and offer a 3d printed tester in either a cheap metal or plastic. The finish of the product still matters.
