Precious Metals
Precious Metals
14k Solid Gold
Offered in both yellow gold and white gold, our 14k solid gold jewelry is made from high-quality ethical gold and stamped with the industry standard 14k or 585. Designed to be worn all day, every day, solid gold is resistant to water and won’t tarnish or discolor. With proper care, your solid gold jewelry should last a lifetime—making these pieces the ultimate way to invest in an heirloom you can pass on to your loved ones while embracing your conscious lifestyle.
18k Gold Vermeil
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. With proper care, 18k gold vermeil jewelry will keep its striking color and shine for years to come. As with all our jewelry, we use only ethical precious metals—a true union of ethics and aesthetics.
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.
Diamonds and Gemstones
Diamonds and Gemstones
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.
Laboratory-grown rubies
Our laboratory-grown rubies are created in advanced laboratories using the flame fusion method, resulting in stones that are chemically and visually identical to natural ruby, with the added benefit of full supply chain control. Used in select designs, lab-grown rubies are the perfect balance for a bold yet elegant styling.
Natural gemstones
Our collections include amethysts, citrines, garnets, onyxes, peridots, topazes, sapphires, and tourmalines, bringing color and personal meaning to our designs. Each gemstone is carefully selected for its quality, beauty, and individuality. Some stones may be gently enhanced (heat-treated, irradiated, or coated) to maximize their natural beauty and achieve lasting color. Where they occur, we disclose these treatments.
Pearls, Mother of Pearl and Shells
Pearls, Mother of Pearl and Shells
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.
