Single stone engagement rings

Rennie & Co handcrafts beautiful single stone engagement rings in London’s jewellery quarter. Our GIA certificated diamonds are set into the very highest quality platinum and 18ct gold mounts, ensuring pieces of breath-taking beauty and durability.

Our philosophy is clear – to make superb pieces of fine jewellery and to offer an exceptional level of customer service unmatched by others. Our solitaire diamond engagement rings available at the Hatton Garden store are destined to become cherished heirlooms rather than being consigned to the scrap pot after a few years of wear.
