Good evening Helen - 15 ct gold jewelry was a favorite during the Victorian era. The problem here, is that there are a few makers that share the initial marks A & W.
We cannot proceed any further without more information. If you are unable to upload a photo of the mark could you provide the following information:
What shape is the A & W in? A circle, rectangle, shield? Is the writing in Script? Is there are decimal point after the A?
This is where a photo really does help and cuts down on time also.
