Sterling silver wedding band style ring: 938,700 ppm Silver & 52,000 ppm Copper (+ Tin, Vanadium & Barium.)

XRF test results for the ring pictured.

This is a really good example of typical total metals content for 925-marked modern Sterling Silver. The two main ingredients in modern Sterling are Silver [usually at least 925,000 ppm — hence the “925” mark, which translates to 92.5% of the total make up of metals for the item], and Copper [normally in the range of 50,000 to 60,000 ppm], along with other trace metals [normally metals not considered toxic (or at least not considered toxic at the levels found or in the specific application — in this case, jewelry)].

I always recommend modern Sterling Silver as a safer choice for jewelry (and for any other items that are available made of Sterling Silver – such as spoons and forks, candle sticks, etc.). Antique or vintage Silver items (including jewelry or food-use items) can test positive for high levels of Lead and other toxicants [you can see an example of that here.]

  1. Hi Tamara!
    Have you ever tested old coins? I have a ring my late husband made me out of an 1895 quarter. Quarters made before 1965(?) Are 96% silver. Is silver a problem? I have no idea what other metals would be in it either.
