Kristina Halladay-Warren is a jeweller living and working in her hometown of Montreal. She studied at L'École de Joaillerie de Montréal from 2012 to 2015 and has been working for the school since May 2016. During her studies she originally formed with three other jewellers a collective named La Bijouterie Mtl. Together they collaborated on thematic collections as well as promoting the work of other Montreal based jewellers. Since leaving the collective, Kristina has been focusing on developing her own brand, Kris Warren, and establishing herself as a versatile contemporary jewellery artist working across different media.

With a keen understanding of form and materiality, Kristina works mostly with silver, pushing the limits of the medium while letting the medium guide her process. Staying true to the principle of form follows function, Kristina's work is both an expression of her personal style and testament to the physicality of the material she works with.
