More long-lasting and resistant to everyday wear than ordinary gold-plated jewelry, our gold vermeil designs feature a thick layer of 18k gold on sterling silver.

Sterling Silver

Sterling silver is a precious metal made up of 92.5% fine silver and 7.5% copper-based pre-alloys. Our ethical sterling silver is loved for its shine and durability, and comes stamped with an industry-standard 925 fineness mark that indicates its purity. Although it's normal for sterling silver to tarnish with time, you can easily polish your pieces to remove the dark patina and help prevent oxidation by wearing your jewelry often.

Laboratory-grown diamonds

BRUNA’s diamonds are created in state-of-the-art laboratories using cutting-edge technology. Make no mistake. Our laboratory-grown diamonds are real diamonds, full stop. From a quality and beauty perspective, they possess the same physical, chemical, and optical properties as mined diamonds—without the negative implications associated with historical mining practices.

Freshwater pearls

All of our beautiful freshwater pearls are carefully cultured and selected. Freshwater pearls form inside freshwater mussels and come in a variety of sizes and shapes that include round, oval, drop, button, and baroque. Pearls are especially delicate, so treat them with extra love and care. More here.

Tahitian pearls

Tahitian pearls are rare saltwater pearls with a natural coloring that ranges from pale gray to black. These treasures are native to French Polynesia and are concentrated particularly around the island of Tahiti where BRUNA’s story began. For jewelry pieces that include Tahitian pearls, we opt to use keshi pearls—a type of pearl that’s known for its unpredictable shape and is historically considered a mere by-product of pearl culturing. More here.

Mother-of-Pearl

Also known as nacre, mother-of-pearl comes from the innermost layer of precious shells. Every piece is wonderfully unique, and can vary in shade from the palest of pinks to soft blue.

Shells

Our genuine shells are sourced from the Philippines. These beautiful products of nature display small variations in shape and coloring—meaning that no two shells are alike.

Enamel

Enamel

One of the oldest techniques of jewelry decoration, enameling is used to add a colorful and glossy layer to our gold and silver jewelry. To minimize chipping from everyday wear, we use a durable epoxy resin enamel instead of traditional glass-based enamel on our designs.
