4℃

4℃ BRIDAL is a bridal-focused division of 4℃, specializing in engagement and wedding rings. Its brand message is “Beauty and excitement for every woman.” Flagship stores and specialty stores offer services such as a lifetime guarantee, Onefinity Diamond, engraving, and semi-custom orders, supporting the selection of rings intended to be worn throughout a lifetime. Canal 4℃, EAU DOUCE 4℃, and cofl by 4℃ also appear within the group’s bridal customer journey, while 4℃ BRIDAL serves as its core line, the one most specifically focused on life’s milestones.

Within the 4℃ group, EAU DOUCE 4℃ is the line associated with a refined design aesthetic and classical expression; the official description says its name means “pure, soft water.” Its defining feature is an emphasis on delicate craftsmanship and material qualities, centered on a harmony of freshness and gentle warmth. It differs from the simple beauty of 4℃ itself and the everyday offerings of Canal 4℃. Rather than being dedicated exclusively to bridal jewelry, it is positioned within the group as an independent fashion jewelry line with a more nuanced mode of expression.

Canal 4℃ is positioned as an everyday-focused line that carries forward the simple beauty of 4℃, which was established in 1972, while offering a wide range of items suited to everyday wear. It is described officially as a brand that “gently accompanies you every day, bringing smiles and courage,” and brings radiance and delight to daily life with jewelry that is simple yet highly fashion-conscious. Unlike 4℃ BRIDAL, which focuses on weddings, and EAU DOUCE 4℃, which takes a classical approach, it offers a broad point of entry that also includes pair jewelry and birthstones. It was announced that the brand would be reborn with a renewed vision on April 24, 2026.

4℃ HOMME+ is a line derived from 4℃, based on the main brand’s simple forms and extending into genderless and ageless demand. It is presented officially as a men’s collection that can be worn for a long time beyond eras and gender, offering rings, necklaces, bracelets, earrings, and other items, including online exclusives. In contrast to 4℃’s main line for women, it addresses demand for men’s jewelry and the unisex category that can be easily shared, complementing the range of style options in a way distinct from Canal 4℃’s everyday offerings and cofl’s theme-specific focus.

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.
