Anyone know jewellery?

[Hullblazer]

I bought a bag of oddments at a boot fair because it contained a 1970s Timex (still ticking), a Montine and and "Exactly".  Amongst the rest of the chaff was this pictured ring.

I like it and it fits (barely) my left pinkie.  But before I wear anything I want to know what it is.

Now, I know it's gold or gold-plate as my father has tested it.  But it is not marked in any way except for the "Gc" on the Onyx(?).

No, it's not bent, the rear 3/5 is chain-link.

Any help would be appreciated!

Very nice ring you have there. Sorry, but no clue as to its origin. Curious myself, though, as wifey and i are going to go shopping for twenty fifth anniversary wedding rings soon.

Cheers!

I may venture and say that the "G" stands for Gorgeous!

Cheers,

If it doesn't have a hallmark.

It might not be gold.

If it is gold and no hallmark it isn't from the U K.

To me it looks like plate.

I agree, I doubt it is from the UK and the weight suggests it's plate too.

Dad's old chemical-kit states it is at least 18k plate though!

if  you can  verify the date (via  some other test) of an "old chemical kit" ;it would be good it still works.    vinn

Not gold unfortunately. The Color is that of 22K and Guess has never manufactured anything in high karat gold, or even low karat to my knowledge. People go to the other "G" brand for that.....Gucci. Additionally, if it were gold it would definitely be hallmarked as its a modern piece not manufactured privately. Im not sure how your father tested it, but if he used the acid test, for a true reading you will have to cut into the ring with the side of a small file to expose the core alloy and place the acid directly on the cut. 

Regardless its a good looking piece so enjoy it, but alas it can't be resized unfortunately.
