Keeping Jewelry Promises: What Labels Like '925' or 'Gold Vermeil' Guarantee

Keeping jewelry promises: What labels like '925' or 'Gold Vermeil' guarantee. In short: What it promises: 92.5% silver, 7.5% other metals (mostly copper). This is genuine silver jewelry. What it reliably: Genuine silver content, which is certified in the EU by the stamp "925" or "S925". Stainless steel fashion jewelry is made for wearing, not as an investment.

As of: September 2026. By Phil, Corelune Jewellery, Düsseldorf.

What it does not reliably: resistant (copper is the usual addition, but other metals are possible), no coating over it (sometimes sterling silver (925) is rhodium-plated, which is to be asked separately). Where to find: On the clasp, on the inside of the ring, on the clasp bar.

Jewelry retailers use many terms, "Sterling silver (925)", "Gold Vermeil", "14k Gold-Plated", "resistant". But what do these terms mean specifically? What is reliably? This guide explains which jewelry promises are really kept and what is behind them.

"925" or "925 Sterling Silver"

Material note: At Corelune you get coated stainless steel, no precious metals with fineness stamp. The alloy specifications above serve for classification. Free shipping from 59 €, 14-day returns.

"585" or "14 Karat Gold"

What it promises: 58.5% pure gold, 41.5% alloy metals (copper, silver).
What it reliably: Genuine gold with officially certified gold content. Mandatory in the EU for genuine gold jewelry.
What it does not reliably: Which alloy metals besides gold are contained (white gold can contain nickel).
Tip: 585 yellow gold typically has copper and silver as an alloy, well tolerated. 585 white gold can contain palladium or nickel, ask about allergies.

"Gold Vermeil" (Pronunciation: Ver-may)

What it promises: At least 2.5 micron gold plating (layer thickness) on a 925 sterling silver base.
What it reliably: A higher gold layer standard than normal "Gold Plated" AND a solid base material.
What it does not reliably: Eternal durability, the gold plating wears off, especially through sweat and friction.
Difference to "Gold Plated": Gold Plated has no minimum layer thickness and no defined base material, can be flash-plating on brass.

"18k Gold-Plated" or "14k Gold-Plated"

What it promises: A gold plating whose gold "purity" corresponds to 18k (750‰) or 14k (585‰).
What it DOES NOT reliably: The layer thickness! "18k Gold-Plated" says nothing about the thickness of the layer, it can be minimal.
Conclusion: "18k Gold-Plated" without further information is less valuable than "Gold Vermeil", pay attention to the additional micron specification.

"resistant"

What it promises: Low risk of an allergic reaction.
What it reliably: Nothing binding, "resistant" is not a legally protected term in the EU.
What it means in practice: Mostly nickel-containing alloys are avoided. The exact composition should be asked about.
More reliable alternative: "resistant according to EU Directive 94/27/EC" is a real standard, allowing a maximum of 0.05 mg nickel/cm²/week release.

"Stainless steel" or "Stainless steel"

What it promises: A certain stainless steel alloy (16 to 18% chromium and 2 to 3% molybdenum) that is highly corrosion-resistant and biocompatible.
What it reliably: solid stainless steel is a standardized steel that is approved for technical applications. The stainless steel at Corelune is nickel-free.

Which material holds up best in everyday life?

How do you keep stainless steel pieces beautiful for a long time?

The most common care mistake is not too little cleaning, but the wrong one. Warm water with a drop of dish soap, a soft toothbrush for the gaps, rinse thoroughly and pat dry. This is the practical advantage over materials that require regular polishing.

When does wearing damage the stainless steel pieces?

The question is rarely whether the material withstands water, but whether tension and friction are involved. At night, moving parts twist and the clasp is under constant tension, which is why chains mostly break during sleep. The point of the matter is not caution, but avoiding the three moments with the highest risk.

Showering, swimming and sports do nothing to the stainless steel, it does not tarnish. For reference, the values from the Corelune range.

Frequently Asked Questions

What is behind the term Gold Vermeil?

Sterling silver as base metal with a layer of gold over it. In the USA, the minimum thickness is regulated, in the EU not uniformly. Without the specification of the layer thickness, the label says little about durability.

What does gold plated mean in comparison?

Gold plating on any base metal, often brass or stainless steel, usually with a thinner layer than Vermeil. What is important is not the designation, but which micron specification is behind it.

What specification should be in every description?

Base metal, material specification or material designation and for coatings the thickness. Formulations like gold-colored or fashion jewelry without addition are not a material specification and do not explain the price.

Can I combine multiple orders?

It makes sense to combine all desired pieces in one order. From two pieces, the volume discount of 20 percent applies, and from 59 euros, shipping is free. Two separate orders lose both advantages.
