Hi Sarah! Never "too late", to educate.
Yep, your reply makes eminent sense. I wondered if your pearl had faded because I was visualizing the deep violet-indigo purple. I remembered the natural variations extant, just wondered if the pearl was delicate, or faded. I just like information...Now of course, you've got me intrigued with the reference to a 'fading' myth, and where and when it started. Anybody?
And now, I have a question. I picked up some shells (and pieces of-) on a beach in FL last winter (please, no lectures on picking up shells...I know, but lots of the shells will just wash back into the water or get buried in the sand, and they do get replenished by currents) and noticed while handling them that the layers of color would rub away to reveal another color. I also noticed that happen in a few of the pearls I've absent-mindedly fondled.
What's going on? is this peculiar to certain kinds of pearls, any information or citations would be appreciated.
