About JM&Co Jewellery

At JM&Co Jewellery, we are a London-based brand creating elegant, sustainable jewellery designed for the modern, conscious woman. Our pieces feature affordable lab-grown jewellery, specifically diamonds, that combine timeless beauty with ethical craftsmanship.

With over 15 years of experience in the fine jewellery industry, Marina has worked in Rome, Milan, and London, gaining global expertise and showcasing our work at the renowned Baselworld jewellery shows, now part of Watches & Wonders Geneva. Julia brings her background in economics together with a passion for art, fashion and ethical business. We founded JM&Co during a time when the world slowed down, and values shifted toward mindful, sustainable living. Together, we launched JM&Co with a mission: to redefine luxury jewellery by making it sustainable, accessible and modern.

Our Values

At JM&Co Jewellery, we believe in luxury with purpose. Our designs are crafted using lab-created diamonds that offer the same brilliance, fire and durability as natural diamonds, without the environmental or ethical concerns. Every piece is set in high-quality sterling silver or solid 14k gold, ensuring both beauty and longevity.

Our jewellery collections range from minimalist necklaces to statement rings, classic diamond earrings and ethical engagement rings. Each design reflects our commitment to creating fine jewellery that is not only stunning but also sustainable and affordable.
