Very old 14k yellow gold thimble with a thimble 14k yellow gold with the lower edge trimmed in an Art Nouveau scrolling floral motif. The polished portion of the thimble is inscribed "MAMcG to AMMcG" (my interpretation, could be wrong). Size 6, has a stamped mark on the side with the number 18. Weight 5.2 grams. Not marked, but does test as 14k gold and is guaranteed to be such. Very good, clean unused condition.
