Good to know
Questions, answered
Everything you need to know about wearing, caring for and gifting your Co&Co pieces.
Is Co&Co jewelry really waterproof?
Yes. Every piece is made from stainless steel finished in 18K or 14K gold plating, designed to be worn in the shower, the ocean and the pool. Simply rinse with fresh water after salt or chlorine and pat dry.
Will it tarnish or turn my skin green?
Our stainless steel core and thick gold layer are made to resist tarnish and fading, so your pieces keep their golden glow wear after wear—without the green marks associated with brass or copper-based jewelry.
Is it safe for sensitive skin?
Stainless steel is one of the most skin-friendly metals available, which is why our jewelry is hypoallergenic and comfortable enough to wear all day, every day.
