Spotted: Bleecker and Broadway, coming from Bianca Lopez's jewelry class

Expert advice:
1) Find a few good investment jewelry pieces you can wear with everything
2) Think of stone colors as makeup-wear colors that brighten your eyes, whiten your teeth
3) Store jewelry separately when traveling (each piece in its own small bag so they won't damage each other)
4) Travel with pieces you never take off or, conversely,
5) Travel with fake jewels
