For sale is this late 1800's, 10k solid gold, inlaid onyx and enamel Knights Templar Masonic Order watch fob or "jewel". It measures over 1 1/2" long x 7/8" wide, weighs 11.1 grams and has no chips, cracks, damage or repairs. The front has the Latin phrase "In Hoc Signo Vinces" In This Sign You Will Conquer, and the back has the keystone with letters (it is monogrammed inside the circle). The onyx have very minor scratching that my camera could not even pick up and I can only see with my loupe. It has been carefully acid tested to be 10k solid gold and has no damage or repairs. It was found on the 10k gold watch chain I'm listing today.
