Composition & Care

Our jewelry is made with care and an eye for quality.

100% nickel free brass

The base is 100% nickel-free brass , a strong and skin-friendly metal that is perfectly suited for gold plating.

2 micron thick 18 carat gold

On top of that, we apply a luxurious layer of 2 micron thick 18-carat gold to the Just Marie Jewellery jewellery, which provides a warm, rich look. The Studio Marie jewellery even has a 3 micron layer.

Nano coating

To protect this gilding we use a nano coating – an ultra-thin, transparent protective layer that helps to retain shine and colour for longer.

Nano coating

Nano coating is an ultra-thin, invisible protective layer applied at a molecular level to the surface of a material – in this case, gold-plated metal. The name “nano” refers to the thickness of the layer: a nanometer is one millionth of a millimeter.

This coating acts as a barrier against external influences such as air (oxidation), moisture, sweat, perfume, and friction. It extends the life of the gold-plated layer and helps to maintain the original shine and color longer.

Nano coating is often used in the jewelry industry, but also in high-tech applications such as automotive paint protection and electronics because of its wear resistance and transparency.

Why brass?

Gold adheres better to brass than to silver, for example. Brass has a slightly porous surface, which allows the gold-plated layer to adhere more firmly. This results in better wear resistance and a longer life of the gold layer, even with daily use.

Care tips for long-lasting beauty

Gold plated jewelry is delicate and requires a little more attention to maintain its shine. Follow these tips for a longer lifespan:

Avoid direct contact with water, perfume, creams and cleaning products.

Remove your jewelry when showering, exercising or sleeping.

Store your jewelry in a dry place, preferably in a soft bag or closed box.

After wearing, rub lightly with a soft, dry cloth to remove skin oil and dirt, or briefly soak the jewelry (note: NOT semi-precious stones) in Hagerty Silverclean and rinse with water.

Still discoloration or oxidation?

Despite good care, the jewelry can oxidize slightly over time, especially if it comes into contact with moisture or skin acids. In that case, you can carefully polish the jewelry with a soft cloth and a little mild detergent or put the jewelry (Note: semi-precious stones NOT) briefly in Hagerty Silverclean and rinse with water.
