Hertta ring, silver

Hertta ring, silver

We coat our bright silver jewelry to prevent tarnishing, so it will shine beautifully for years to come. Our pieces are handcrafted in Kuopio from 100% recycled materials.

Hertta is a romantic interpretation of the classic heart motif. Its organic design wraps the heart in slender, flowing lines, adding layered depth and gentle movement to the form. The collection is a delicate reminder of connection and warmth—a gesture of gratitude cast into shape.

All Lumoava jewelry is designed and manufactured in Finland.

Our over 80 years of experience and the uncompromising craftsmanship of our goldsmiths are evident in every detail.

Our jewellery has been awarded the Key Flag Symbol, which indicates Finnish work and origin. We also participate in the Ekokompassi environmental management system, which supports our continuous efforts to develop and improve our environmental responsibility.

We only use durable and high-quality materials in our jewelry.

14K yellow gold is a chemically almost inert metal. It does not oxidize or rust, which is why it retains its luster and beauty practically forever. The gold we use is 100% recycled.

Sterling silver is a durable precious metal that darkens naturally due to the effects of sulfur compounds in the air. Patina does not weaken the metal and it can always be cleaned and polished again. With proper care, silver can last almost indefinitely. The sterling silver we use is 100% recycled.

Bronze, the main material of the Lumoava Studio collection, is an alloy of copper and tin, of which approximately 88% is recycled. Bronze patinas over time to a greenish hue, which is why our bronze jewelry is finished with a high-quality precious metal coating that protects the surface and gives the jewelry a lasting shine and precious sparkle.

Plating finishes the surface of the jewelry and makes it durable. We use 14K yellow gold and rhodium plating, which give Lumoava jewelry its recognizable bright glow and protect the surface from wear. In the Studio collection, we also use a palladium base coating, which creates an even base and beautiful tone, on top of which a layer of either gold or rhodium is added.

• Yellow-gold plating is a coating that we use on both silver and bronze jewelry. It finishes the surface with real gold and makes it glow, valuable and durable. Gold plating does not react with chemicals, but its wear is mainly affected by mechanical abrasion – that is why re-plating is recommended for rings when necessary. With the right coating thickness, gold plating will last the entire life of earrings, pendants and bracelets.
  
  
• Rhodium plating is a coating that we use on silver, bronze and white gold. It helps the jewelry retain its bright shine and stay beautiful for a long time. Without rhodium plating, silver and other metals react easily with oxygen – just like silver spoons, which darken if stored in a box and only used on special occasions.

Our jewelry is handmade from 100% recycled silver and gold at our jewellery factory in Finland. Each piece is a sustainable and ethical choice, and by acquiring our jewellery, you can support Finnish work.
