I have a necklace that was going to be for my girlfriend but we broke up. It is still in the box and never been taken out. It still has the price tag on it thats $200. It is 1.5 CTTW. If you send me your number I will text you pics. I’m wantting to trade for a cheap 4 cyl car or roller. Open to all other stuff to! It would be a good christmas present! Thanks for reading!
