Diamond Necklace

what hints can i give about a sapphire & diamond necklace?
I told my girlfriend that i bought her christmas gift already & she wants hints to what it is. i already told her the first hint “her b-day” because i bought her birthstone-sapphire. I got her a very nice sapphire & diamond necklace and i really dont know what hints to give her without giving it away. Any ideas on clever hints to give her? i want to keep it a surprise though.
that’s the thing. If she managed to find out what it is, she will be hugely disappointed because she spoiled the surprise.
I would not give her anymore hints even if she nags you to death, lol. It’s all part of the surprise.
