Looking For Info On An Ancient Ring

mmgregory: to the CCF! Coinincidentally, there is a rather extensive chain of Gregory jewelers stores in Sydney.

In your case take this ring to a jewelry or bullion dealer, and have the ring tested - using XRF.
If it is ancient, there should be trace amounts of elements that the ancients could not refine out. The presence of trace elements other than the intended alloying metals would be a sure indication that the ring is of ancient origin.

It appears that it may be a more modern signet ring, that has suffered the effects of in ground burial for some decades.
Worth an XRF test anyway, just to assess the purity.

mmgregory;

Looking back at the 2019 records, this is all I come up with so this may not be one of the Donald Jackson pieces after all. (When I replied to you on ebay saying here is where the Donald Jackson ring information is.) So that link won't help you sorry I assumed when you mentioned a ring it was one of his. When I buy estates of ancient coins I find things like this and here is the record of your sale.

Powerful Braided Design Ancient Roman Bronze Ring US Size 5-6 (16-17mm)
Order status: Paid

Thus I may have had no other information on it myself. The ones from Donald Jackson I knew a lot more about. So that is all I know. But as others have suggested there can be some information based on what the ring itself presents and the XRF idea is not a bad one that was suggested to you.
