I picked up a silver looking handmade heart shaped box today. The weight is right, slight magnetic. Silver acid is brown, might have old acid... Looks to be reacting with the metal and a light blue color on the ends of the circle. Not marked anywhere I can see...
Scratch test with 18k gold acid makes the silver dissolve. The silver acid on the dot didn't look like it etched the piece at all.
18k acid right on the piece results in a blue/green? Dark spot after cleaning off the acid, look like some copper showing up at the edges. I'd say that it's plated. After hitting it with some sand paper, it looks like a copper hue. I'm still going with plated
