All Lumoava gold and diamond rings are made in Lumoava's own jewelry factory in Kuopio, Finland. Each ring is handcrafted by our goldsmiths with over 80 years of expertise.

We use 100% recycled 585 gold. The gold is not mined, and we recover all the precious metal that is produced during manufacturing – including dust – to minimize material waste and environmental impact.

Yes. A lab-grown diamond is chemically, physically and optically a real diamond. The difference is in how it is created: a natural diamond forms in the ground over millions of years, while a lab-grown diamond is grown under controlled laboratory conditions.

The choice is always the customer's. A natural diamond is unique and limited, a traditional store of value. A lab-grown diamond, on the other hand, often allows for a larger stone within the same budget and is produced without mining. Both are excellent quality options.

The natural diamonds are sourced from a Finnish supplier that complies with the Kimberley Process. The diamonds are not from Russia and meet the requirements of EU and G7 sanctions. Lumoava's laboratory diamonds are also sourced through the Finnish company Timanttiala Oy.

The rings are made to order just for you. Normal delivery time is about 2 weeks.
