What’s a birthstone?

Not really flirting, but my bf gave the best gift. We’re exchanging Christmas presents, and I get a necklace that is just one big sapphire. I instantly gush, and happily exclaim “You got me my birthstone!”

Bf looks at me confused and says? ” Birthstone? I don’t know anything about birthstones, I got it because it reminds me of your eyes.

I instantaneously melt into the floor. He meant it too. 😍
