Polku ring 5mm, Silver

The timelessly personal Polku.

We coat our bright silver jewelry to prevent tarnishing, so they can shine beautifully for many years. We handcraft our jewelry in Kuopio using 100% recycled materials. A jewelry gift designed to last is also a responsible choice.

All Lumoava jewelry is designed and manufactured in Kuopio, the world's northernmost jewelry factory.

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

Our jewelry has been awarded the Key Flag label, which speaks of Finnish work, and we are part of the Ecokompass environmental system, which supports our continuous work in developing environmental responsibility.

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

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.

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 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 14 carat 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.

• 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.
