Sara Chyan explores the unique temperature-aware colour and geometric shapes of bismuth to create stunning one-of-a-kind jewellery pieces.

When heated, bismuth changes colour from brown to bright rainbow hues. As the metal cools, the metal reforms into intriguing shapes. Sara takes advantage of these properties to create earrings, pendants and rings that are truly one-of-a-kind. Each piece is handmade, ensuring that no two pieces are alike. Whether worn as a conversation starter or simply as a beautiful accessory, Sara's jewellery is sure to turn heads.

About Our Leather
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. Each colour reflects the different temperatures the material has burned at. When oxidised, bismuth creates these gorgeous palettes, in a wonderful display of light and colour.

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 is lovingly handmade in the UK, using traditional methods combined with a contemporary aesthetic. 


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. Sara draws inspiration from nature and architecture, as well as the muted colours and textures of landscapes. 


Whether it’s a pair of statement earrings or a delicate necklace, each piece is made with exceptional care and attention to detail. Sara’s jewellery has been featured in multiple publications, and she has exhibited her work internationally. Her clients include private individuals, as well as high-end retailers such as Design Museum, Selfridges and Harrods.
