I have noticed some pearls that are so lustrous that they look fake, but these were shown to me by 2 jewelers that I trust. The first were Tahitians that were so silvery and green, but I didn't see any core color. The second was a strand of FW pearls that looked like beams of light. I would have guessed that both were fake because they looked too shiny and glassy. Could this be because they were AAA quality and I'm only used to A/AA? Honestly, I didn't like them that much. Is this a matter of taste or maybe I just need to cultivate my preferences?
