This is a vintage 10K gold filled 1960s Western Electric service pendant that belonged to a member of my family. The triangular pendant was made by L. G. Balfour. It measures 1 inch x 1 inch, weighs 11g, and is marked LGB 1/5 10K GF on the back. There is an inset for a 0.05ct melee diamond near the bottom but the gem is missing. Other than that, it is in nice vintage pre-owned condition. See all pics. Will be carefully packed and quickly shipped.
