Questions to ask
- Does it have luster, an "inner light?" It should.
- How is it shaped? Perfectly round is most valuable, though some prized pearls are very irregular.
- Is the color evenly dispersed?
- On a necklace, is the strand tightly strung? You want to see the pearls, not the knots between them.
