We at JCO London are a customer centric bespoke jewellery company specialising in diamond engagement rings, wedding bands, anniversary rings, earrings, pendants, necklace, and fine jewellery. We are based in the heart of Hatton Garden, the world-renowned diamond and jewellery district. Our family business grew out of their need to provide for their family but blessed that it was driven by both of their passion for jewellery and precious stones. Not only our parents had a skill for business and an eye for the right stone, but also poured their passion into designing their jewellery with gold and platinum metals.
