    Ah, Douglas, everyone was so patient with me, in all of my ignorance and enthusiasm. I think the truly funny bits are in Kevin’s/Terry’s post.

    I still have one strand of my sorely abused pearls, which escaped further abuse while I mulled.Click image for larger version

    1)stopped the process before the thread dissolved, but after a little bleaching
    2) the thread had dissolved but look at was under the dye layers!
    3) again the thread had dissolved, but I’d forgotten these in-solution for a day and a half, so much more the original pearl.

    You can see at a glance why some of these were consigned to the dye-lot; from sorting distance and in a bunch, they’re Meh. Individually, some are intriguingly lovely.

    much to be learned, of course now I know the ‘carapace’ consisted of well-bonded aragonite and conchiolin layers, and where it separated was a not-successful bond.

      I was enamoured with the ones that yielded a frosty look. I think they’re called ripples now, but for me the frosties are a tad different.

      who could not love this pearl?

      I tried to make this side by side, but didn’t manage it.

        Not only these, but! On my first eBay forays I got some pearls from China, and I thought What the???? What the heck am I supposed to do with these???
        I think Im seeing, now. Im grateful I have these treasures, and I hope the drillers and sorters are still employed, and are appreciated. Im straight as an arrow, here, not at all under the influence

        ...this is the Secret World that Peter Gabriel is singing about. I hope I can capture this pearl.

          These are all little, and the way they’re drilled, there’s a beautiful side, then you flip it and there’s the secret world.

          Much prettier irl.

          I feel a rope coming on. I definitely didn’t ‘see’ these pearls 10yrs ago. There should be plain white pearls, or Rice Krispie pearls between.?.
          Play time at last! COVID and winter doldrums relief. I hope I feel the same way about these tomorrow.

            Glad to see you having fun with experiments and thank you for sharing the results. I love to find the "Secret World" in everything that captures my imagination...yeah, great Peter Gabriel fan here (mea culpa, will scratch your back).
            The color is peachy-lavendery, nice and I would add stark-white rice krispies if you have them...they would look nice

              Neat science experiments lisa c. It's always good fun making ropes. You have to post the results when you are done.

                I have some old akoyas that now have cracks like that, but the cracks are my own fault. I wore them every day for over 10 years, and I bought them used/old from an antique shop, in good shape but not superb, dulled by dirt, but no cracks until...

                Anyway here's the story - there was a thread on Pearl Guide way back when about restoring yellowed pearls to white again. I tried most of the remedies. One suggested that rehydrating them in the sun was a good idea. The sun warmed the water, and they did look a little better...I took the idea too far, figuring that warmer water = warmer nacre, which would rehydrate faster. I put them in warmer and warmer water until unfortunately, the last time I looked some were cracked.

                The nacre expanded more successfully than the bead? or is the bead intact and some of the innermost nacre cracked? At least the surface layer of nacre expanded and contracted without a crack.

                1)Not one of my cracked beads has a surface crack, and
                2)size of the bead doesn't matter and
                3)the cracks are 2 yrs old and haven't spread to the surface. So, that's my result after 2 yrs - but what does it matter since the appearance is unsightly whether or not the crack progresses? Well, any increase in knowledge is of benefit, of course.

                I think impact as a cause would show a crack through the outermost layer of nacre. There are a few PGers who've broken pearls deliberately - I hope one of them will take up the thread here, but

                - if someone doesn't the topic has probably been addressed in one of the threads on the forums.

                I'm going to leave here and check through the archives, but for now you know at least one cause - hot water, no matter how slowly you heat it up.

                I'll be checking on the damage that sonic cleaners do next.

                In the meantime, though this is very tardy "Welcome to Pearl Guide!", and I hope you've stuck around in spite of the topic not having been taken up. There's a world of knowledge here, and really good people.

                Hey, you're already a pearl-guy! and probably already know this stuff! Dang! Don't I feel stupid.
                Well, at least you're still here, right? and posting, etc...and you can do your own checking!
                I have seen this happen over the years to necklaces we have strung. My conclusion is that eventho the nucleus and the coating are essentially the same there are chemical differences and physical differences which force them to expand and contract at different rates.

                  for all the Pearl Girls
                  have brought their hammers,
                  to add to their test-i-mony...

                    LOL Lisa C... I like your Humor!
                    Talking about Hammers & Pearls...been thinking I should talk with Taika Waititi and have him do a "Thor" movie called "Mjolnir and Pearls", having Natalie Portman wearing looooots of pearls.
                    Years ago, I did a video on how I cracked some Cortez Mabe with a hammer, to demonstrate how tough these pearls are. Of course, they did break...but if I had a diamond it would have also shattered, I am sure (BTW: anyone has a diamond I could use to experiment on?)

                          Hi Charlotta! Yes, well, these were the get-rid-of-the-dye experiments. I was obsessed with all things pearl, in a more impulsive than scientifically controlled way. I had only pennies and ‘late nights on eBay’, but lots of fun

                          Step 1) Get more thread and needles
                          1a) Clear a space
                          Step 2) Get all of my pearls in the same place.....
                          Step 3) Warm up by hopping around to Peter Gabriel Live In Your Eyes with Yousson Dor and Jennie Abrahamson. Hurt my knees badly, so sit down with pearls....

                          Douglas! I love your videos.
