We welcome you to visit our Newcastle studio to experience our designs in person.

As many of our pieces are made to order, not all styles are held in studio at all times. We recommend contacting our team, prior to your visit to confirm availability of a specific design.

We offer a complimentary 3 month warranty on our fine jewellery pieces. You can read more information about our warranty terms here.

Q: Is the Diamond Heart Charm Necklace solid gold?

A: Correct! The Diamond Heart Charm Necklace is crafted in solid gold or silver.


Q: Can I add a Diamond Letter Charm to this piece?

A: Yes, they can be purchased here.

Q: Am I able to add more Diamond Heart or Diamond Letter Charms at a later date?

A: If you were hoping to add charms at a later date we require you to send the piece back to us as the holes are so small on the charms that they don't simply slip over the clasp. Our jewellers will need to remove the clasp, add your new charms and solder the clasp back on. Otherwise, you can have a local jeweller add the charm on for you and resolder the jump ring.

Q: Are the white gold Diamond Heart Charm Necklaces rhodium plated?

A: As standard, our 9ct white gold Diamond Heart Charm Necklace is not rhodium plated. Our 9ct chains are rhodium plated— but charms are not. You can add this service to your piece here. Our 18ct white gold pieces are either rhodium plated or upgraded to platinum at no additional cost.
