Metal Detecting

Hi nipped on to the sand last evening and was on for a few strides and got a nice sharp signal found the target straight away at first glance in the sand thought it was a ring it was of sorts a ear ring qiuit thickish and at first as it felt quite light so I thought it may be rubbish jewellery,when we drove home I showed the item to my partner and she said it looked like old {white gold} so this morning had a closer look with a loupe and the markings if anyone knows what the mean is a square symbol which I camnnot make out and then the numbers 375 and at the moment that all I can make out maybe someone out there knows what this means.

hi

the 375 would correspond with the assay mark for 9 carat gold.

if you could clean up the ring you might be able to make out which assay office and year that it was stamped.

Neil

you should find several symbols

firstly a sponsors mark (normally the maker) this is usually a minimum of 2 initials and a shield design

secondly the millesimal fineness mark 375 for 9 carat 585 for 14 carat and 750 for 18 carat and 916 for 22 carat

thirdly the assay office mark

and there should also be a letter which corresponds with the year the piece was assayed

Hi and thanks I can make out the 375 as I say the first symbol looks like maybe a tudor rose or similar but not sure I am using a 30 x 21mm loupe would a stronger one help to identify or we just looking a 9ct 375 uk standard the earing is quite thick but seems very light, the markings are on the pin which goes through the ear lob.

a tudor rose would be the sheffield assay office

Hi thanks again as this earing is quite thick would the ring be solid in gold,also looks like whie gold which made me think it was rubbish,also the hallmark is on the pin that goes through the ear,what really baffles me why an earing on the beach with the pin in the closed position I can understand if in the open position and lost?

Paul

This is the earing hopefully it all gold and not just the pin.

Hmmmm....I think if the hoop was gold it would be hallmarked on the inside edge.
Probably plated I think.

Yes this is what I thought at first sight my partner thinks it is a gold called rose gold something I quite frankly have never heard of.

Paul

Rose gold is as said a red rose colour and bye the way white gold is just ordinary gold that has a silver plate.

"The whole thing will be gold not just the pin if hallmarked, probally hollow if its very light but still gold "

I'd have to disagree with that, Chris. If the hoop is made from base metal and just the pin is gold, then the pin will carry the obligatory fineness mark (eg. .375) as items of
less than 1gram in weight are not required to display a full hallmark. But if the whole item is made from gold of the same purity then the mark would be on the main body of the item as per assay office regulations.

No, earrings are very often only hallmarked on the posts, the earring will still be all 9ct gold, not worth very much though if it's very light. The gold is mixed with copper to give it that 'rose' or 'red' gold colour.

yep thats true sanna, and what happended to my post? who edited it? lol
