The perfect jewelry from the combination of steel & carbon
The combination of a black stainless steel chain with an octagon (8 corner) pendant made of 100% genuine carbon fiber shows you two unique materials that are made for each other.
Classy & Smooth Black Rope Chain
Your chain made of 100% stainless steel has a length of 55 cm for the perfect fit at chest height and can be closed with a secure and simple clip closure.
Unique carbon pendants
Your Octagon pendant is milled from 2mm thick carbon sheets using precise and complex CNC technology.
Afterwards, each carbon blank is sanded by hand and given a protective glossy finish by us, which allows the unique carbon marbling to shine.
Wear your carbon chain every day
We know you never want to take off your Octagon Necklace, which is why we made all CRBNCNCPT necklaces 100% waterproof, sweat and heat resistant to withstand even your most adventurous lifestyle.
