Need help identifying my Grandma's jewelry

Hello! Title has the short form, but my story goes like this:

I have recently been helping my mom pack up to move, and she found her mom's old jewelry box. It had some pearls and thin chains, but the stand out item to me was this crest. It has a thick gold chain that is about necklace length attached to the ring on the top.

The piece is bent and the center (rimestones?) is noticeably off-centered. My first impressions were that it looked like someone tried to cast their own house crest or some other story following amateur craftsmanship. All that to say that when I told my mom this theory she mentioned that apparently my grandmother had a close familial relation to a Canadian Armed Forces service member we also theorized that maybe it was a recreated signet or something. I bit down on the end of one of the swords to get a feel for the material and it kinda crunched under a light bite. I almost want to say whatever it is made of is only plated in gold.

I unfortunately dont have the family history to know anymore details, nor have my grandma alive to ask herself. I'm just taking a shot in the dark that maybe someone on Reddit recognizes something from the visual aspects. Thanks in advance
