Vintage WWI French 75 cannon necklace. "Notre Porte Bonheur" - our good luck. The 75mm field gun (known in French as Canon de 75 modèle 1897 but commonly referred to as the French 75). It is widely regarded as the first modern artillery piece. The necklace is in OK condition. There is a crack in the glass on the back. The front still looks good as the grass (?) hides the crack.
