Gold bangles- no hallmark

[QueenofLouisiana]

I have received 3 gold bangles, originally owned by my grandmother. She always wore them and I believe that they date back to the 1950s/1960s. She lived in Aden and Caracas at this time and I think they are probably from the Middle East, likely 18/22k gold.

However, they have no hallmark. There isn't any sort of marking other than the pattern. I wear them all the time and they leave no black marks, don't tarnish etc. They are still very shiny, despite the fact that they are likely to be about 65 years old. While they are narrow, they are very heavy.

Any idea how I would get them tested, valued, whatever...?

You can get them assayed to confirm that they are gold, and I believe they will then be hallmarked and then you can get them valued.

There are a few assay offices throughout the UK

Hallmark is a British thing. They won't be hallmarked if they were bought abroad.

You can get them tested at many jewellers and also those places that buy gold. However, I would have them done twice at different places, especially if the first says they aren't gold but 'quite pretty pieces, I'll give you a tenner each'.
