What is Hallmarking?

Hallmarking is the practise of marking precious metals with symbols and numbers, in order to prove the value or type of metal used to create jewellery. This legality was first enforced in 1973, and primarily helps to protect buyers from fraud, but also offers a form of identification. Hallmarking essentially proves the metal or jewellery has been independently tested and certified.

Hallmarking at MAC

MAC is delighted to announce its new partnership with The Assay Office - a company which hallmarks silver, gold and precious metal jewellery.

From this partnership, a custom hallmark for MAC has been developed which incorporates the hexagon shape to mark the important achievement following our 60th-year celebrations, which occurred in 2022.

This Spring, we are thrilled to announce that from this partnership, we will be offering our course participants and tutors the opportunity to send their jewellery created within our Creative Courses to our partners The Assay Office, where it will be officially hallmarked.

MAC will also be offering a 10% discount on personal hallmarking with Assay Office and an additional discount on jewellery courses for all jewellery bookers here at MAC.

60 years of jewellery making

This partnership was introduced in celebration of MAC’s 60th birthday in 2022. We are proud to have been offering creative courses for all, for over 60 years. This hallmark partnership with Assay Office is an important milestone in MAC’s Creative Learning programme.

Two pairs of earrings with MAC hallmark

I came across these earrings almost a year ago and shared the story with my sons of which they did not know. I found out the old photo and the plans that I have saved, and how at the age of 17 it was at MAC that they were made. Seeing this, a personal memory, that I enjoyed and was so much fun. They booked me onto the same MAC course in 2021 I now have two jewels and two photos 40 years apart, and another lovely memory to hold dear to my heart.
