is it worth comparing conch and melo with pearls from this article? After all, outwardly they are similar and have flames:
Although after reading this article to the end, I, like the authors of the article, realized that it would not be possible to fully understand the structure of pearls until they cut it in half.
And if, for example, draw the structure of the growth of melo/conch pearls, with layers similar to an onion, then how to depict the tongues of flame on the sketch?
This is really interesting
I don't think there was ever a satisfactory explanation for the formation of these (assuming the vortical form observed via transmitted light is not a surface phenomenon).
Nice of you to post Ana's paper I did not remember it...it was so long ago and with so many things happening. Man, I remember John Lennon's lyrics "Life is what happens to you, while you're busy making other plans..." with all of this information.
Anyway, this has become a very interesting thread and its due to the "spark of curiosity" and then the rich information that is shared. Thank you all
