A symbolic necklace for my GF? Dating for 3 months.

I want to get my girlfriend a meaningful necklace. She gave me a small statuette that perfectly represents me, and I really love it - so now I feel like I want to give her something equally thoughtful in return, that describes us, or just her personality.

I’m thinking about a gold-plated necklace with a Morse code message - maybe with our initials, or a word that carries meaning but isn’t too intense yet, like “I love you,” since it still feels a bit early for that.

What would be your suggestion?
