I think it's a big difference between if someone genuinely likes the style, or if it is used as a social measurement.
I volunteered at the D'Knight's school last year, helping out in the computer lab. One of his classmates always came up to me, and she always wanted to see what necklace and earrings I was wearing, and she wanted to know all about them.
I don't know how much she learned about computers by the end of the school year, but she is the only 9 yr old I knew who could tell the difference between Old Mine, European and Brilliant cuts.
She liked jewelry, and she never saw her mother wear anything other than a wedding set. So I was the adult she knew who would be willing to talk to her about pieces, let her hold them and look at them through a loupe.
I was invited to the class end of the year party. The girl came up to me and thanked me, and told me:
"When I'm older, I'm going to have diamonds just like yours.
But mine will be bigger"
