Gold-Filled vs. Gold Vermeil vs. Gold-Plated

Gold-Filled vs. Gold Vermeil vs. Gold-Plated: The Real Difference

All three look like gold on day one. What separates them is how much real gold there is and what sits underneath, and that decides how long a piece keeps its color. Here is the plain-English version, based on the U.S. Federal Trade Commission's Jewelry Guides.

Quick answer: Gold-filled jewelry has the most gold of the three. By FTC rules, its karat-gold layer must be at least 1/20 (5%) of the item's total metal weight. Gold vermeil is sterling silver with at least 2.5 microns of gold. Gold-plated jewelry can carry as little as 0.175 microns of gold. For jewelry you wear every day, gold-filled is the longest-lasting option short of solid gold.

Side-by-side comparison

	Gold-filled	Gold vermeil	Gold-plated

Gold standard (FTC)	Karat gold layer at least 1/20 of total metal weight	At least 10k gold, minimum 2.5 microns thick	Electroplate: minimum 0.175 microns
How the gold is applied	Bonded with heat and pressure	Plated over silver	Electroplated
Everyday wear	Made for it	Good with gentle care	Best for occasional wear
Price	Mid-range	Mid-range	Lowest

What Mondsee uses

Most Mondsee jewelry is 18k gold-filled, made to the 1/20 standard: the 18k gold layer is 5% of the piece's metal weight. 18k gold is 75% pure gold, compared with about 58% for the 14k gold many gold-filled brands use, which gives a warmer, richer color. Our pieces are handcrafted in Brazil, hypoallergenic, water-resistant and tarnish-resistant. We also carry a smaller line of .925 sterling silver and moissanite pieces, a few 18k gold vermeil styles, and we label every piece by its material.

Browse the gold-filled range: paperclip chains, Cuban link, rope chains, figaro chains, gold hoop earrings, ear cuffs, tennis bracelets & necklaces and anklets.

How to care for gold-filled jewelry

Wash with mild soap and water, then dry thoroughly.
Rinse with fresh water after the ocean or pool.
Keep it away from cleaning products and harsh chemicals.
Apply perfume and lotion first, let them settle, then put your jewelry on.
Store pieces separately in a clean, dry place.

Frequently asked questions

Is gold-filled jewelry real gold?

Yes. Gold-filled jewelry has a real layer of karat gold bonded to a base-metal core. Under the FTC Jewelry Guides, an item can only be called gold-filled if the gold layer makes up at least 1/20 of the total metal weight. Mondsee's gold-filled pieces use 18k gold for that layer.

Which lasts longer, gold-filled or gold vermeil?

Gold-filled usually holds up better to everyday wear because its gold layer is much thicker. Vermeil needs only 2.5 microns of gold over sterling silver, while gold-filled requires the gold to be at least 1/20 of the total metal weight.

Is gold-filled better than gold-plated?

For everyday wear, yes. FTC guidance lets electroplated gold be as thin as 0.175 microns, so plating can wear through quickly. Gold-filled has a far heavier layer of gold, so it keeps its color much longer with normal care.

Can you wear gold-filled jewelry every day?

Yes. That is what gold-filled is made for. Remove it before using cleaning products, spray perfume before you put it on, and rinse and dry it after the beach or pool.

What does 18k gold-filled mean?

It means the gold layer is 18 karat gold, which is 75% pure gold, bonded to a base-metal core. Many gold-filled brands use 14k gold (about 58% pure); 18k has a richer, warmer color.

Does gold-filled jewelry tarnish?

Genuine gold-filled jewelry is tarnish-resistant because the surface is real karat gold. Keep it away from harsh chemicals and store it dry to keep its shine.
