This is a very nice service award (35 years?) issued by Bank of America featuring 3 diamonds and a sapphire mounted in 14K gold with a weight of about 1 dwt (1/20 troy oz). On the back it is stamped 14K EMB CTO. It measures about 5/8" x 3/8". The connecting ring used to attach the charm to the bracelet or necklace is not soldered so I do not know if that is gold. There is still a little bit of surface dirt adjacent to the stones that is visible under magnification and some light surface wear from normal use.
