Jewelry makers are taking a shine to these nontraditional metals. (These materials don't all have standard markings.)
Like the look of white metals? This may be your new love. It's half the weight of platinum, more than 12 times harder, and paler in color but just as shiny. Palladium is also much cheaper than platinum.
Hypoallergenic and durable, with a satin finish, stainless steel is expanding beyond the kitchen and into the jewelry box.
Feather-light, this silver gray metal has the strength of steel, and it's hypoallergenic and corrosion-resistant. Like stainless steel, titanium costs less than some white metals but more than silver.
