It takes a great deal of courage to become an antiques dealer. And, I feel it is a useful experience to jump into the deep end of the swimming pool and swim with the sharks. Hopefully you will not drown.

But may I make a few generic suggestions?

1. Examine one bead at a time.
2. Try not to let pride get in the way.
....Humility will take you much further.
3. Do not rely on hearsay alone as evidence.
4. Always show respect for the opinions of others.
5. Try not to mix authentic beads with dubious ones.
6. Avoid asking for opinions on beads you are trying to sell.
