Swift Values
Expert Guides

When you inherit jewellery, the quickest way to understand what you are dealing with is to check the hallmark. This small number tells you the purity of the metal and is one of the most useful details for a probate valuation.

You do not need any specialist equipment. Almost all hallmarks are easy to find and even easier to photograph.

Where to Find the Hallmark

Rings – inside the band
Chains & necklaces – on the clasp or small tag
Bracelets – next to the fastening
Earrings – on the post or butterfly back
Bangles & pendants – along the inner edge or on the reverse

Only look for hallmarks on items that feel like solid precious metal. Very light or hollow pieces may not have them.

What Does a Hallmark Look Like?

To the naked eye, a hallmark can look like a tiny scratch, a row of dots, or a slight blemish on the metal.

In reality it is a short line of very small stamped impressions:

• There are often 3–5 tiny marks in a row.

• Some may be symbols (for example a lion, crown or letter).

• For probate, you only need to focus on the number in that row.

If you cannot read it:

• Open the camera app on your phone.

• Hold the jewellery steady and zoom in.

• Take a close-up photo – this usually makes the number clear enough for us to read.
