Leo Costelloe (b.1993) is an Irish-Australian artist living and working in London.

His work in glass, metal and silversmithing explores the transient and sentimental nature of objects. Drawing inspiration from popular culture, spiritual practice and personal experience, Costelloe creates sculptural works that situate themselves in a liminal space somewhere between beauty and banality.

Costelloe graduated from Central Saint Martins with a BA (Hons) in Jewellery Design.
