Have a look on this "calcareous concretion"!

[meredith]

Hello! I want to share with you here what was recently found inside the Tridacna shell in the waters of the remote island in the Molucca Sea. Can hardly call it a pearl but it's a beautiful formation! It's about 50 gram piece.

What an interesting piece!

Those look like calcified gonoducts. I've seen it mussels, but in clams it's really rare.

Do you have other information or photographs?

 

[Katbran]

Well that's really interesting !

What is the size in millimeters? It's difficult for me to transpose grams into a size. And are there photos of the other sides? Yes, fascinating piece. Thank you, Meredith!

Wow. That's different and quite cool.

BRAINS! We now have zombie pearls.

BRAINS! We now have zombie pearls.

lol - that's what I thought when I saw it, looks like brains!

Much prettier then the usual lumps that come from Giant clam.

BRAINS! We now have zombie pearls.

LOL ! Good one!

 

[meredith]

Hahaha! Maybe we can start to call it a pearl with the brains!? The size is approximately 45x40x20 mm and here are some more photos. You can see the place where it was attached to.
Thank you for your opinions!

Meredith, that's beautiful, amazing and wonderful! And remarkable to have the original shell as well ... well done!

Meredith,
Now this is even more fabulous! Having the shell it grew in adds value if you decide to sell it, and certainly adds to our knowledge! Also is a size that could be made into some type of jewelry item. Are you planning to keep it?

That is really cool

 

[Katbran]

Wow...thats fabulous ! I love these photos ! It reminds me of live coral.

super cool; I think it would've been better left on the shell as a neat display!

Agreed. It's always advised to preserve value because anything cut can be deemed as damaged or destroyed.

In this instance though, a clever crafter can work around this problem. In reality, it happens a lot with pearls, for example drilling at a blemish or filing the back side of something to fit a bezel.

Such an interesting piece!

Thank you so much, Pattye, Katbran, CathyKeshi ea, for your kind comments here! Great to hear that the piece is of interest! By the way, it was already loose, out of the shell. But it was not difficult to discover the place where it was attached to. When sitting on its place, it obviously belongs there. It would be nice to keep it for myself but I will not hesitate to sell it when I find out what it's worth and when I find a buyer.
