Hello, I am setting an old engagement diamond (0.46 carat, average quality cut) into a necklace for my daughter's 18th birthday. My daughter is a small size 4 and still dresses in jeans and t-shirts most of the time. I was looking for something classic that she can wear for years to come.
My questions are ... what length should the necklace be? Do you have suggestions as to how it should be set? What do you think of the example in the picture? Thanks!
