Our great quality guarantee

Marmara Sterling specializes in handcrafted jewellery, merging high-quality European crystals with sterling silver components. Being a responsible company is paramount to us, which is why we utilize 99% recycled silver in our creations. Our designs are largely inspired by the latest trends in crystal shapes and colors. Nonetheless, Marmara Sterling is committed to designing and producing pieces that are uniquely characteristic of our brand.

Sterling silver

All our earrings, pendants and rings, among with most of the other metal parts, are manufactured using 99% recycled silver. Silver is called sterling silver when the silver content in the metal is equal to or more than 92,5% (hence the name 925 silver). Thus all of our jewellery bears the 925 stamp, alongside with the name stamp of our company (required by the Estonian Law of Precious Metals).

Rhodium plating

As sterling silver alone oxidizes very easily, which can turn the metal black, all of the silver parts in our jewellery are rhodium plated. Rhodium is a rare metal (in fact more expensive than gold) that doesn’t scratch and prevents the jewellery from oxidizing, so it will maintain it's shiny look for a longer period of time.

Gold plating

Half of our jewellery selection features gold plating, catering to clients who prefer gold. This is achieved through a process akin to rhodium plating, but with 18K gold instead of rhodium. Details about the various platings are available under the individual product information.

Our zirconia

We use the most diamond-like zirconia stones in our products. We guarantee that their production, materials, cutting, and polishing are of the highest quality, ensuring that these gems will last for years. Their colors will continue to delight with exceptional resistance long after your purchase.

Crystals

Marmara has used and will use only the finest quality crystals produced in the European Union. The stones we use are man-made, but made with precision-cut using quartz, sand and minerals. The production and processing is very complicated. Cutting hard materials like crystals and gems involves a complex process due to their hundreds of identical facets in various directions. Each facet's reflection of light must be calculated by a computer, then simulated in 3D, optimized, and ultimately translated into control programs for sophisticated machinery.

Stainless steel springs

Stainless steel is a hypoallergenic material, widely used for jewellery and watches. We use stainless steel instead of silver in the clips of our Alcantara bracelets and in the springs of all basic earrings. Silver is too soft to be used for this purpose so this process is needed to ensure you don't lose your earrings.
