How do I identify a maker?

Makers stamp their pieces with specific hallmarks, initials or full signatures on the reverse of the metalwork. Examining the back of a brooch or pendant usually reveals these small maker marks alongside silver purity stamps. Researching the registered punch marks of Scandinavian silversmiths helps confirm the origin of unmarked or signed items found across the inventory.

What is guilloche enamel?

Guilloche enamel involves mechanical engraving of precise geometric patterns onto a silver base prior to glazing. Translucent enamel is then fired over the engraved metal to create shimmering light effects. This technique appears frequently on mid-century butterfly and floral brooches originating from Norwegian workshops.

How should I clean enamel jewellery?

Enamel requires gentle handling because harsh chemical dips or ultrasonic cleaners can damage the glass glaze and weaken the metal. Warm soapy water and a soft cloth are sufficient for removing surface dirt. Careful drying prevents moisture from lingering around stone settings or pin hinges on vintage brooches and necklaces.
