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.

Platinum Metal

Platinum is both rarer and stronger than gold and perfect for realising the beauty of diamonds

Yellow Gold

Yellow gold is a traditional choice, and can give a certain vintage-look to engagement ring designs

Rose Gold

Rose gold exudes a unique charm, perfect for unusual engagement rings

White Gold

White gold is made up of alloys that are less expensive than platinum, meaning it can be a cost-effective choice
