OP here! I really enjoyed (most of) those comments! This actually happened about 10 years ago xD I did call her out on it and told her I hand-made mine. She reluctantly handed it over, which she wouldn't have done if it was REALLY from her sister! For those saying I could've shown a picture- again, 10 years ago haha. Phone cameras were pretty crappy and less popular. Plus I only had the necklace for about two weeks. All's well that ends well and let the stealer go sulk to her friends!
