Sonar is all about gold, yellow and white, worked over in different ways.

The jewellery is either presented with a rustic surface, a signature of Per Borup Design, or a polished look for festive occasions, set with or without brilliants.

​

Two wavy curves make up the basic design element of the collection, which is repeated in echoes throughout the line.

In order to reach this equally minimal and elegant expression, goldsmith Kell Borup first experimented with seven different waves in multiple sizes, before he decided on the selection as shown.

The waves work effortlessly whether seen as a singular shape or paired up in three-dimensional arches.
