GA hallmarkings
by: Tommy S

Did you ever get to the maker of this GA in a rectangle hallmarking? I have inherited a diamond white gold bracelet with the exact same markings as pictured on the gold ring in this post.

[GA] ⚖️ 375 🌹

DIA 0.50

From what I’m gathering above is that the maker is unknown, the gold is 9k and it was from Sheffield in the 1970’s, and it has half a carat in diamonds.

Really interested to find out more about it if possible. It has a lovely catch and is really well made. Would be a shame to scrap it.

Good morning, I have purchased a ring which has hallmarks just like this one. The rose for Sheffield, 375 indicating 9ct gold and I think one of the other marks is a set of scales above the number 375 which I have determined as the 'common control mark'. The makers mark is GA in a simple rectangle. There are other marks DIA which indicate the diamonds and a number for their carat. I would really like to find out about the makers mark... it is my only stumbling block. Could you shed any light on this at all?

Any Joy?

I too have a ring which has the same hallmarks. It was my mothers engagement ring. Although the one I have is cz and the hallmarks are impressed rather than embossed.

The Crown on Sheffield Plate
by: Iris

Good morning,

I collect Sheffield Plate and to the best of my knowledge after 1815, a CROWN, the Sheffield town mark, was unofficially used to distinguish high quality pieces from continental plated wares. Kind regards Iris

Sheffield Town Mark | Crown

Hi Steve,

thanks for your imput!

I've been trying to find an image of a set of British hallmarks with the pre-1975 Sheffield town mark. Would you have any ideas?

with regards

Yes, its 9ct and hallmarked in Sheffield. The scales are the "convention mark" sometimes known as the "common control mark" or CCM.

There are a number of countries in the European hallmarking convention all of whom have similar hallmarking regulations. Items marked with the CCM can be traded between member countires without the need for further testing and hallmarking.

It's not necessarily an import mark though as many UK manufacturers have the mark applied so that they can export their goods easily.

GA might refer to a jewellery company based in Leeds called Abbeycrest (they used to be called Gallery Abbeycrest, so GA), but to be sure you'll need to contact the Sheffield Assay Office.

As Yvonne already mentioned, George Angel was an older silversmith.

GA in a Rectangle & Sheffield rose mark
by: Anonymous

Hi Lucy thank you for writing to us. Good for you for purchasing a secondary piece and helping to lesson the impact on our environment! These marks are British Hallmarks.

The rose at the end is the Town Mark, it is the Sheffield Rose (it was formerly a crown). The crown mark was used from the start of the assay office in 1773. The crown was the town mark for Sheffield UNTIL January 1st 1975 when it was changed to a rose.

we can tell from the town mark that the ring was assayed in sheffield AFTER 1st January 1975.

Next to the town mark, we have the gold standard mark. 375 is just another, more technical term for - 9ct gold.

9ct gold, by the way, is the most hard wearing.

The next two marks aren't so easy. There should be a number between the scales, but I think it may have worn away, despite the fact that the ring is relatively "modern", as we know from the town mark, the item was assayed in or after the year 1975. It was obviously well loved :-)

Why I feel the scales is the UK mark on 18ct, 14ct & 9ct GOLD on LOCAL & IMPORTED WARES [the number varies] - ca 1975 - Present - is because the impression of the shield around the scales is telling and is an exact match. The dates are also in keeping with the town mark.

The maker's mark is problematic. A quick search brings up George Angell 19th c./2nd half, however the GA for George Angell appears in a quatrefoil and the initial marks on your item appear in a rectangle.

Lucy, I might get my friend from the London Assay Office to have a look at this maker's mark. It may take some time before you receive a reply, but you should get an email notification when someone replies to your question, each time. (if you checked the notification box after you submitted your question)

In the meantime, you might be interested in reading a good guide to Hallmarking in Great Britain Here.
