Our Materials

All stilnest jewelry pieces are available in either solid gold, gold vermeil, rose gold vermeil, or silver. It is our goal to be as sustainable as possible from sourcing the precious metals to you receiving the final product. While we are on a journey to become as sustainable as possible in every aspect, we want to give you full transparency regarding your product already today.

Gold Vermeil

Let’s start with the basics. For a jewelry piece to be vermeil, the base must be sterling silver, the purity of the gold must be at least 10 karats, and the thickness of the gold plating must have a minimum of 2.5 microns.

Our gold vermeil jewelry pieces are available in 18K rose gold and 24K yellow gold. The base is composed of 92.5% silver and 7.5% copper. By alloying it with copper, the jewelry becomes harder and thus more durable. For our gold platings we use 100% recycled gold from our partner in Antwerp, Belgium. The thicker the plating, the longer it lasts. For our plating, we use at least 2,5mc and up to a 5-micron plating. The high majority of our raw materials comes from recycled sources from the watch and jewelry industry that we can track down to the refinery. This way, we aim to contribute to a circular economy and reduce our carbon footprint to a minimum. Still, for some products, having full transparency on the highly complex material flow is not possible at this point. We only work with partners that are certified and part of the ‘Responsible Jewellery Council’ to ensure that all materials are obtained from conflict-free regions.

Recycled 14k Solid Gold

For our solid gold jewelry, we use an alloy of 58.5% fine gold and 41.5% mixed metals to keep its preciousness while making our jewelry durable and scratch-resistant. The majority of our solid gold pieces do not have plating and are considered waterproof. During the refining process, the CO2 emission is kept to a minimum, resources are preserved, and thermal energy used.



To avoid differences in color, some of our jewelry receive additional plating. This is the case for chains and studs. For our gold platings, we use 100% recycled gold from our partner in Antwerp, Belgium.

925 Silver

Our 925 silver jewelry receive a rhodium plating to protect the silver from tarnishing and scratching. It not only makes the surface harder, but it also gives each jewelry piece a shiny gloss. Rhodium is considered the rarest and most valuable precious metal in the world.
Our 925 silver jewelry is composed of 92.5% silver and 7.5% copper. By alloying it with copper, the jewelry becomes harder and thus more durable. Silver can get recycled and reclaimed without any loss of quality or changes in the material. The high majority of our raw materials comes from recycled sources from the watch and jewelry industry that we can track down to the refinery. Still, for some products, having full transparency on the highly complex material flow is not possible at this point. We only work with partners that are certified and part of the ‘Responsible Jewellery Council’ to ensure that all materials are obtained from conflict-free regions.

Stones

It is our goal for our Fine Jewelry to not only look great, but to also be manufactured under fair conditions. We therefore use fairly and responsibly sourced stones.

Real Diamonds

We only use “conflict-free“ diamonds that align 100% with The Kimberley Process (KP) to ensure that they are not illegally traded to finance wars against the government. Our fairly sourced diamonds are cut and processed in Sri Lanka and get set in precise craftsmanship in Germany.

Gemstones

Fairly-sourced Gemstones

We use both Swarovski crystals and fair gemstones. Our fair stones are sourced directly from the mines that are known by our partners in person and cut in Germany and Sri Lanka. We can therefore trace back the origin of each stone while ensuring a fair, sustainable, socially responsible, and traceable supply chain. Products featuring fairly sourced gemstones are marked as such in our store.

Non-traceable Gemstones

We receive some of our gemstones from partners that source the stones from big jewelry markets. Since the stones are already mixed and sorted by quality and color, it is impossible to trace back their exact origin. We source our stones from German suppliers that are certified and part of the ‘Responsible Jewellery Council’ to ensure that all materials are obtained from conflict-free regions.
