Immortal Quality & Hallmarking

At IMMORTAL JEWELLERY, we are committed to providing the highest level of quality and assurance to our customers. While in the UK there is a legal requirement to hallmark precious metals over the weight of 7.78g, we go above and beyond to ensure that every piece we create is marked with our unique hallmark.

We take great pride in the craftsmanship of our jewellery and believe that every piece should be of the highest standard. That's why we take our jewellery to be tested and hallmarked at The Assay Office in the heart of The jewellery Quarter in London, UK, even for pieces that fall under the legal weight requirement.

This extra step not only ensures the authenticity and purity of our precious metals but also offers peace of mind to our customers that they are purchasing a piece of jewellery that has been thoroughly inspected and meets the highest standards. We are dedicated to providing our customers with jewellery that not only looks beautiful but is also of the highest quality.
