At Mariri Jewels Ltd, all our jewellery pieces weighing over 7.78 grams are hallmarked in compliance with UK law. Hallmarking is a legal requirement that guarantees the precious metal content in our jewellery, ensuring authenticity and quality for our customers. Every piece we create is crafted from 925 sterling silver, a mark of superior quality and durability. It is both our guarantee and our duty to ensure and uphold this standard. Mariri Jewels is proudly registered with the Assay Office in Birmingham, one of the UK’s official hallmarking centres. This means every hallmarked piece from Mariri Jewels carries the Assay Office mark, our Sponsor’s Mark, and the Fineness Mark, providing you with complete transparency and confidence in your purchase. Trust Mariri Jewels for genuine, high-quality jewellery that meets the highest standards.
