Engraving (with Marie-Josée Roy): The works listed in the Artwork > Roy-Prieur section are pieces that Marie-Josée Roy has conceptualized and executed, which Jérôme has embellished and enhanced afterwards. There are others where Jérôme isolated the imagery, Marie-Josée created the piece and he added the finishing touches by engraving on it. The works are always made on aluminum, brass, copper or steel.

In early 2018, Prieur began adding a new dimension to his paintings and drawings. His new works include engraved acrylic panels that cover the painting, much like a glass frame. Prieur reinvents this classic framing method by adding engraved details onto the acrylic, which then become part of the piece.

In 2020, a new collaboration (Amer-Prieur) of the artists Amer Rust and Jérôme Prieur was born. Created with the movement and fluidity of the rust and the finesse of the engraving, their aesthetic is what is most present at first sight. The message beyond the technique of each work is free of interpretation. However, their subjects, result of their common vision, are based on their view of our society, beliefs, symbolisms and the observation of the dark side of the human race.
