Learn About Metals

Hearts of London use only the highest quality gold and platinum alloys to ensure the perfect finish for every ring. All the jewellery we craft is officially hallmarked at the London Assay Office, assuring the quality and purity of the metals we work with, and carries Hearts of London’s unique sponsor mark. Metals can vary vastly in durability, which is why we tend to work with only platinum, and 18ct golds - the optimal metal options for aesthetically pleasing hues and sufficient durability. Our clients can enjoy a life time of complimentary cleaning, polishing and resizing.
