Sustainability & Materials

At Omasi, we are committed to crafting our jewelry from responsibly sourced materials mainly within the EU and are continuously working toward partnering exclusively with suppliers who hold a Chain of Custody (CoC) certification from the Responsible Jewellery Council (RJC), ensuring traceability, ethical practices, and environmental care throughout the supply chain.

A share of each online purchase is donated to the PLANET Foundation, allowing us to give back and support environmental initiatives with every order.

14K GOLDFILLED

We choose 14K Goldfilled for its durability and lasting shine. Unlike traditional gold plating, a thick layer of 14K gold (585, 1/20) is bonded to a brass base using heat and pressure, our Goldfilled pieces contain roughly 5% gold by weight, 50-100 times more than standard gold-plated jewelry. It's not solid gold, but with proper care it's built to keep its beauty for years to come.

STERLING SILVER

Our 925 Sterling Silver is valued for its quality, durability and bright, warm shine. It's hypoallergenic and nickel-free, making it a good choice for sensitive skin.

At Omasi, we prioritize sustainability by using recycled silver whenever possible, ensuring that our jewelry not only looks beautiful but is crafted with care for the environment.

CULTURED FRESHWATER PEARLS

Cultured freshwater pearls are grown inside freshwater mussels, each one forming slowly and slightly differently from the next. That natural variation is part of what makes them beautiful, no two pieces are ever quite the same.

SILVERFILLED

Silverfilled follows the same principle as Goldfilled: a substantial layer of sterling silver bonded to a base metal, rather than a thin plated coating. It offers the look and feel of solid silver with added durability for everyday wear.

GOLD-PLATED SURGICAL STEEL

For pieces made from surgical steel, we use a gold plating chosen for its durability and comfort against the skin. A lightweight, hypoallergenic option suited to jewelry you want to wear every day without a second thought.
