De Rerum Natura Bérénice

Bérénice is unlike anything else in the De Rerum Natura range — a luminous, cloud-soft lace yarn that transforms every project it touches. Knit alone, it creates a diaphanous, frothy fabric full of movement and light. Held alongside Ulysse or Gilliatt, it adds a discreet shimmer and irresistible softness that makes their colours glow in an entirely new way.

Built around a lustrous mulberry silk core, its extra-fine RMS-certified mohair and organic Mérinos d’Arles fibres are carefully combed and spun into a yarn with generous volume but a surprisingly refined halo — fluffy without being overwhelming. Dyed with GOTS-compliant, eco-friendly dyes, it’s a yarn made with as much care for the planet as for the knitter. Perfect for lace shawls, lightweight layering pieces, and as a held companion for sweaters and accessories.
