Bielander's work investigates questions about identity, affiliation, judgment, and perception—how it is steered and how one can shift it. His trompe-l'oeil pieces feature immediately recognizable yet disconcerting objects such as prawns, pineapples, beetles, or raspberries, setting up humorous interplay between wearer and jewellery. His iconic "Cardboard" series exemplifies this approach: gold meticulously crafted to mimic corrugated cardboard, subverting hierarchies of value and preciousness.

Bielander describes his artistic philosophy as walking "that fine line between making something simple enough that one unavoidably recognizes, that simultaneously requires a fair conscious effort to get beyond the obvious". He seeks materials and techniques that simulate reality while maintaining conceptual abstraction.
