Vintage Scovill outlet 10k Gold & Sterling Service Award Company Tie Tacs - Enamel

I have tested the unmarked one and it held up for 10k and 14k but will only figure it in the price for outlet 10k.

The diamond one is marked 10k LGB and the silver one is marked Sterling.

Size:
Silver: 13.67mm x 11.65mm, 1.7grams
Gold: 13.5 x 11.61mm, 1.6 grams
Gold with diamond :14mm x 11.75mm, 1.6 grams

These come from the original recipient with the L G Balfour Co Box.
