Sinua

Sinua

Sinua is a Finnish jewelry brand specializing in earrings designed specifically for adult women. Sinua earrings are designed and crafted in Finland, combining abstract art with high-quality materials.

Johanna Lehto founded Sinua in 2024, and her love for art and creativity is evident in every piece. The jewelry’s surfaces are adorned with stunning patterns created using acrylic paints, reflecting her artistic vision.

The primary material of the earrings is Finnish birch, symbolizing the qualities the designer hopes women will discover within themselves. The metal parts are made of high-quality 925 sterling silver, finished with 18k gold plating, adding a touch of luxury.

Sinua’s Finnish-made jewelry is a symbol of courage and individuality. The earrings encourage women to live life unapologetically and on their own terms—regardless of age.
