I got my first set stainless steel dice many years ago (decade or more) from https://crystalcaste.com/. They have since changed the style of their dice to something I don’t particularly care for. I also have a set of anodized aluminum dice but the coloring is worn off in places (very minor but enough for me to notice).
If you use a dice tray, they don’t pose a hazard to gaming tables. However, I have found annoying scratches in them when I stored them in a dice bag by themselves.
