Pearls need a bit of moisture, but not more or less. Conchiolin, the cement of aragonite crystals of pearls, is a protein we can compare to the one making nails and hairs (horns too), mentioned by BWeaves. Then, we may better understand how moisture works on a pearl. Too much moisture softens...

BWeaves, each kind of living organism has its own process to absorb water it needs (water is never a production, it's already first in nature). We drink to do that, but, for exemple, vegetables, bacterias, and many lower organisms absorb water through their "skin" bathing in water or humid...

As Pearl Dreams says, "water is water". Any organic tissues always contain water (that's the fundamental element earth environment offers to build the life), and this water always contains a bit of salt itself, but an amount without relation with living environment. For exemple, flesh of...

I agree, two part epoxy glue is the best. Ordinary cyanoacrylate glues are not good glues, they don't resist to vibrations and often make white aureoles on pearls under moisture, even a long time after gluing. For more safe about final look, it's better to choose transparent epoxy, even it has...

Yes, GemGeek, they could be very fashion in some clubs! Massive aragonite has also a variable fluorescence, from yellow to strong pink and orange colours, under UV long waves, but this small reaction of tahitian pearls is worried, maybe dark conchiolin makes a barrier for this light?

pattye, thank you for sharing. The pink is clearly visible, looking like some aragonite massive stones...But nothing similar with tahitian pearls, a mystery:p

Thank you for sharing, GemGeek and morella. Strange nacre reactions under UV! Aragonite stone turns to yellow, up to strong pink and orange, enlightened by long waves UV. Is it the same with pearls? That's difficult to see with the purple background of photos.

Nice pearls, morella, whatever their origins! And I love the combo. Just a thing I don't understand, it's this curved shape of the back of mabe. Is it carved shell's nacre of the one which have produced the mabe, or a glued piece? It's not easy to make this kind of piece, that makes me think of...

Yes, Orient, "conchyoline" is a french word...:rolleyes:. Sure Hisano has well seen any kinds of internal pearls structures. It seems these non-nacreus parts inside pearls can contain several organic materials, more or less degraded. That would be interesting to know why oysters or mussels...

Thank you, Orient. Small non-nucleated structures of these Akoya pearls look like tahitian ones. Are like-void parts in Xray full of conchyoline, like seen on tahitian pearls views?

Very good article too, Orient, thank you for sharing. I am so interested by what's happening inside pearls... And what you are showing us is significant about complexity of pearls growth, especially for every baroque shapes ones.

So interesting article, Orient! Thank you for sharing. It shows clearly any nacre discontinuities which can be found inside tahitian pearls, and their relations with shapes. For exemple, the back part of pearls circles seems to match a high organic material concentration, like any drop shape...

Very interesting explanation, Pearl Dreams. I might add that this phenomenon of thin nacre turning in blue on a conchyoline brown layer can be met on surface of thick nacre freshwater pearls. I think some disturbance during time to grow makes mussel to produce these layers, without aragonite...

Truly wonderful brooch. It looks like an Art Nouveau design, but contemporary work, in fact. I wonder if broochs are appreciated, again. A recent time ago, Ladies didn't like to see their clothes drilled by this kind of jewel.

Parrot Lady, your necklace is gorgeous! Difficulties to appreciate golden colour of this kind of pearl come from great influence of screen colours calibration on such special tones. Neither screens have the same calibration, none between a PC and a phone one.

Wow, BWeaves, many things have changed, since last time I have gone to Amsterdam. It was more a quiet town! A jam of bicycles, like in China, but thirty years ago... maybe the march of progress is going to pedal?:rolleyes:

lary007, the shape of your nice edison pearl is a rare perfect tear drop! BWeaves, I agree you, Amsterdam is a magical town, like any built above waters (Venise is an other jewel)). It's a long time I haven't seen Amsterdam, are there always most number of ladies on bicycles? A time ago, only...

You are right, Katbran, weird beads jumping out of tenticles, in a restaurant, the good beginning for a novel of Poe or Lovercraft;)

Opus Magnum, the Great Work, to create such gold wonder!

Interesting points of view, la_corsetiere and GemGeek. Many natural singularities are not listed, specially about see life, not yet so much well known than terrestrial. In tropical oceans, I have found myself curiosities I have spent several years to understand, without any known scientific...
