As an online-exclusive sustainable line derived from 4℃, cofl by 4℃ uses recycled metal and lab-grown diamonds and promotes “a beautiful relationship between the Earth and jewelry.” It gathered momentum in 2022, marking the 50th anniversary of the 4℃ brand, and also directs 1% of sales toward forest conservation. Bridal jewelry was added for the first time in 2024, while its role within the group is distinct from the wedding-focused remit of 4℃ BRIDAL: it brings in a new value standard centered on environmental consideration.
