ATR Hallmark Signet

This ring stands as a celebration of our hallmark issued by the London Assay Office.

Each hallmark issued symbolises a moment in space and time, validating the quality of your piece but also eternalising it with the year and location of its creation.

At the top is our maker's mark, and below that the marks given to the piece once it has passed regulation confirming the level of fineness of the material, the assay office and finally a letter signalling the date of issue.


  • 16mm diameter signet
  • 3mm depth

All our pieces are made from 100% recycled materials and all gems are lab-created and ethically sourced.

Please note that handmade items may vary and our details below are averages dependant on size.

Through wear and tear it is normal to see surface scratches or marks, however please take care by removing your jewellery at the end of the day, before strenuous activities and when washing.

Avoid exposing your jewellery to harmful cleaning products or cosmetics.

We recommend using warm soapy water and a gentle brush to clean jewellery as it gathers dirt over time.

All pieces are handmade to order so please allow for 4-6 weeks for the piece to be cast, hallmarked, polished and shipped to you.

As all pieces are made to order they are therefore non-refundable apart from exchange or credit. For more information, please check our full Return Policy.
