Bismuth earrings


Bismuth is a rare low-melting-point metal. It is commonly used in fire detection systems, electrical fuses, stomach medicines, cosmetics and pigments and bullets. But we use it in jewellery. The oxidation of bismuth is spectacular, where natural crystalised forms and colours can tell us the temperature. One colour represents one temperature, so it makes each piece exceptional.

Temperature plays a major role in this project.  Changes in temperature can lead to changes in the physical forms of the chosen metal.  This transition between solid and liquid phases caused by heat gives the metal an emotional character and transforms the metallic jewellery into an emotional symbol. 


All of our jewellery are lovingly handmade in the UK.

As a professional maker based in London since 2018,

Sara Chyan enjoys testing the limits of what materials can do, and is fascinated by how particular items can be created in unique ways.


We believe the aim of every project is to craft well-designed works of art that are beautiful and functional. Above all, our passion for design and creation comes from the desire to bring incredible ideas come to life.
