Can gold-filled tarnish? Yes, it can, but it takes a rare set of circumstances. Gold-filled jewelry supplies are a lifetime product because the gold layer bonded to the brass core is quite thick. However, in rare instances of extreme sulfide exposure, it can blacken.

How long will gold-filled jewelry last?

Most high quality gold-filled pieces have the same appearance as high carat gold, and gold-filled items, even with daily wear, can last 10 to 30 years though the layer of gold will eventually wear off exposing the metal underneath.

Is gold-filled tarnish resistant?

Gold filled jewelry, on the other hand, will only tarnish under unique circumstances. Pure gold pieces barely tarnish, and even though they're an alloy, the heavy layer on gold filled jewelry protects against tarnishing. We recommend that wearers clean gold filled pieces with mild soapy water or untreated cloth.
