AN Antiques Roadshow expert has revealed the simple way to find out if your old jewellery is worth a fortune.

The BBC One shows sees lots of people bring in stunning items, with no idea of their value.

Fiona Bruce was told how to spot when gold jewellery is the real deal

Members of the public regularly bring in pieces of gold to be valued

But expert Joanna Hardy explained to host Fiona Bruce how to figure it out, and it's not too complex.

Standing in front of three rings, Fiona admitted they all looked like gold, and Joanna said: ...You are right. They do look like gold, but two are brass with gold plate and one is nine-carat gold.

“Now you would not know which was the gold one unless it had the full UK hallmark, and by law post-1950, jewellery must be sold with a full UK hallmark....

She continued: ...So you will have a makers mark or a sponsors mark, you will have the fineness of gold, meaning it’s either going to be nine or 18 or 22-carat gold.

...It will have the assay mark, which in this case is Birmingham which is the anchor sign, and then you have the option of a date letter.”

Fiona asked: ...If it has been made after 1950 and it doesn’t have a hallmark, you don’t want to touch it?...

Joanna replied: ...No, this has been a real increasing problem with people buying items on the internet.

...People will see a ring described as gold and say, nine  'carat ' or 18K,  'carat ' it means nothing, it could still be brass with gold plate.

“It has to have the full hallmark, and we have here an example of a silver full hallmark which has to only be done by the four assay offices in the UK.”

Meanwhile, the episode saw a lady discover a beautiful diamond ring was worth £1250.
