4C is a jewellery collection of necklaces and earrings made of recycled sterling silver. The pieces show diamond outlines instead of real stones, offering an ethical and ecological alternative to genuine diamonds. The shapes are created with 3D modelling, wax printing and lost wax casting, and are then assembled and finished by hand. Four cuts are included: brilliant, princess, marquise and pear. Polished, matte patina and gilded finishes add contrast and highlight the three-dimensional form of each piece.
Press Kit
- Unique Properties
- 4C jewellery collection provides a new way to wear diamonds and acts as an ecological and ethical alternative to genuine diamonds and their sparkle and status.
The diamonds in the collection are made with 3D-technology to resemble the outlines of different gem cuttings created with precise mathematics and technique, and show the beauty which is usually left unseen.
There are four different cuts; brilliant, princess, marquise and pear, and a limited edition heart cut.
The different finishes; mirror polish and matte patina or gilding, provide contrast to highlight three-dimensionality of the collection. - Dimensions & Packaging

- Production Technology
- Design was created with 3D-modeling, high resolution wax printing, and lost wax casting in recycled sterling silver, made by advanced professionals. It's assembly; soldering, filing and sanding, and finishing; polishing, matte finishing, gilding and patina, is made by hand with traditional goldsmith work.
The 3D-technique was chosen to support the idea behind the jewellery collection; precise gem and diamond cutting practise. - Design Challenge
- The design challenge was to create jewellery which is beautiful and delicate by itself but at the same time would play as a conversation starter about ethical and ecological aspects. The design provides light and shadow in its finishing to support this point.
The realization challenge for me was to step out from my comfort zone and instead of creating jewellery collection by hand I was to choose computer aided 3D technology, which offers the perfect tools for this project. Accurate enough 3D wax printing technology had entered in the industry just in time. - Project Duration
- The project started in the beginning of 2017 with the first necklace and earring set. The whole collection, four different necklaces and a dozen different earrings, was finished in September 2020 in Kuopio, Finland.
- Operation Flow
- 4C necklace is a long, solid chain with a small and large diamond pendant. Small diamond connects the chain which works without a lock. The necklace is put on easily just by hanging it around one's neck.
Individual pendants in omega chain have a silver carabiner lock in the chain.
Different versions can be used separately or layered for a more prestigious gala styled look. - Research
- Project began as wire jewellery tests made first in metals and paper. Accurate 3D wax printing entered in the industry to create precise models and print as wax to cast them in silver.
Details in gem cutting is the hidden gem in the industry. At the same time ethical perspective of gems is the talking point in our field. The 4C collection points an ethical view for this and shows the beauty of the diamond cuts by four most familiar cuts. 4C is a statement piece for the user and the designer. - Inspiration
- The name of the 4C collection comes from the components that affect the value of the diamond: cut, carat, colour and clarity.
Stripping a prestigious and valuable diamond into a wire pattern puts it in a new light. The removal of the sparkle gives space to the shape and the jewellery becomes a very graphic object, the inner and outer surface of which can be viewed at the same time.
Ethical and ecological aspects of the diamond industry are the talking point right now. 4C collection are jewellery with diamonds without diamonds. This is my statement piece. - Image Credits
