Koa crafts thoughtful, coastal-inspired, ethical jewellery.

Fresh designs

Having made the commitment to be a sustainable jewellery brand very early on, we have continued to grow and develop with our focus always on less harmful practices over profit. Koa’s lines are always designed to be as uplifting in their ethical nature, as they are in their simple style and selective use of colour.

So shop our vibrant and innovative collections of earrings, necklaces and cuff bracelets, always with the knowledge that each and every piece is handmade for good. With a fresh vibe, carefully selected coastal tones, and a simple Scandinavian style, Koa’s unique designs, while accessible to all, will have particular meaning to anyone choosing to live a more conscious lifestyle.

Our home and studio is situated just a short distance from Cardiff, in South Glamorgan. With a beautiful coastal outlook, we are a dedicated independent Welsh Jewellery business that is constantly striving to make improvements. The rewards for this have always come in the connections we have made with like minded individuals and other small businesses.
