About Us
At CMJ London, we specialise in luxury, custom-made leather and gemstone jewellery for men – though our designs are loved by anyone who values quality craftsmanship and timeless style.
Founded in 2012 by Carla Marie and her family, what began as a small workshop quickly grew into a recognised brand. Word spread fast – people wanted jewellery that was personal, durable, and affordable without compromising on style.
Every piece is still hand-crafted to order in our UK studio. We use only the finest materials – genuine leathers, natural gemstones, sterling silver, and gold – to create jewellery that’s both modern and meaningful.
Because we believe jewellery should feel like it’s truly yours, many of our designs are fully customisable. From hidden engravings to personalised sizing, we make sure each piece is as unique as the person wearing it.
