Amadeus only uses sustainable materials in all jewellery.
Most of our jewellery is made in vermeil - recycled sterling silver covered with a fair trade pure gold layer of at least 2 microns. This is five times thicker than average gold plating and more durable.
Some of our chains and thicker earrings are made in gold plated brass with at least 2 micron thickness of solid gold. We also add a layer of anti-tarnish to further improve durability. The reason we chose to use brass instead of silver in some pieces is because is it a very sustainable material and to keep the price point at an affordable level. Our brass is 100% nickel-free and cadmium-free.
