What is gold-filled jewelry?

June 5, 20261 min read

Quick answer: Gold Filled = 5% gold content by total weight, mechanically applied. More durable than gold plating (10–30 years), but not solid real gold.

Gold Filled means that at least 5 percent of the total weight consists of gold – mechanically bonded to a base metal (usually brass). This is far more than normal gold plating and makes Gold Filled significantly more durable – but it is still not solid real gold.

Gold Filled vs. Gold Plated vs. Real Gold

Gold Plated: 0.05% gold – lasts months
Gold Filled: 5% gold – lasts 10–30 years, looks identical
Real Gold 585: 58.5% gold – lasts a lifetime, has material value

Is Gold Filled hypoallergenic?

For most people, yes – the gold layer is thick enough that no base metal comes through. In cases of severe nickel allergy, reactions can occur if the layer wears through.
