Tests don’t lie. - See that lovely GREEN spot on the testing stone? That’s from this crap silver. I bought it over a year ago and finally had it tested. The first clue was how yellow it was. I’m sorry but, 92.5% silver and 7.5% copper do NOT create a yellow alloy. The other red marks are from actual .999 silver. Green = -.500. Yup, that’s right - less than HALF.
