Information about gold-filled
Is gold-filled the same as gold plated?
No, gold plating is a minuscule layer of solid gold applied to a brass base. The plating does not compose any measurable proportion of the product's total weight. It is estimated to be 0.05% or less of the metal product. Gold plating can wear off quickly and expose the brass base product. It does not stand up to heat, water or wear over time. By comparison, gold-filled contains 5% gold by weight. All the gold is on the surface which offers product protection from tarnish and wear. Read more on gold-filled vs. gold plated.
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.
- Foreign transit through extremely polluted shipping docks has caused the product to blacken on several occasions.
- Products stored in nail salons with high levels of chemical sulfide fumes are at risk of blackening.
- A fire where the structure filled with smoke caused blackening
These are extreme conditions. However, it has made me think twice about breathing the air in nail salons! Gold-filled usually just requires light surface cleaning with an untreated cloth or mild soapy water.
Can you be allergic to gold-filled?
Individuals who have skin reactions with gold alloys will also react to the gold alloy layer on the surface of gold-filled. Some people's body chemistry will cause their skin to blacken or develop a rash when they wear certain metals. I am one of those people and on certain days, my fingers will turn black all around my 14kt wedding band. Rarely, an individual's body chemistry may darken the metal as well.
