I have a 9k albert watch chain with the same M & M makers mark but it also has the Birmingham mark but no date letter. The only way to roughly find out its age would be to identify the M&M makers can anyone help?
Comment: We need to see the marks to assist you further. Sincerely Yvonne

Scottish Makers Mark on Antique Opal Ring by: Yvonne Hammouda-Eyre
Hi Stacy I'm presuming your antique opal ring originates from Scotland. Are there any other marks on the ring, a date mark?
Without being able to examine the ring, the "M&M" is probably the sponsor's mark, (not initials) sometimes called a makers mark.
Your opal ring sounds lovely, however you have to be careful with antique opal jewelry as opals are soft gems and tend to deteriorate over time, especially if not stored carefully.
