Our Quality
Good jewelry starts with what it is made of. Here are the metals, finishes and stones we choose—and how to keep them looking their best.

925 STERLING SILVER
925 sterling silver is the core material across almost the entire Roberta Amsterdam collection. Made from 92.5% pure silver and alloyed for added strength and durability, it offers a polished finish with the substance to be worn again and again. Every design is nickel-free, and the exact materials are clearly listed in the Quality section of each product page.

18K GOLD PLATED
Across the collection, our gold designs are finished with warm 18K yellow gold. The exact base material and finish are clearly stated in the Quality section of every product page.

RHODIUM PLATED
Rhodium is a precious metal chosen for its bright, polished shine and added surface protection. It gives each design a refined finish and helps protect the surface.

5A–8A CUBIC ZIRCONIA
We use high-grade 5A and 8A cubic zirconia selected for clarity, precision cut and light-catching sparkle. Tinted stones add colour while keeping the finish refined.

MOISSANITE
Moissanite is chosen for its brilliance and durability. Its clear, light-catching sparkle gives every design a bright, polished finish.

SHELL PEARLS
Shell pearls are crafted using mother-of-pearl material and finished with a smooth outer coating. Their even shape, high-luster surface and classic look bring a polished softness to each design.

Care
Yes. Every Roberta Amsterdam jewelry design is nickel-free and made with comfortable wear in mind.
Your jewelry is made to be worn often. To keep it looking its best, follow one simple rule: last on, first off. Let perfume and lotions dry before wearing, wipe gently after use and store each piece separately. An occasional splash is nothing to worry about—just dry it gently.
