Thanks for your translation, @Pearl Dreams!
It looks like a typical Osmena nautilus shell cabochon to me. The 3rd picture shows the pattern of the shell. I like your 1st picture, very pretty.

Beautiful ring... "IRID PLA" should be Iridium Platinum alloy. There is plenty info online about this alloy for jewelry.
My wild guess about the pearls is Akoya and color-treated Akoya. How big are they? Any info when she bought this ring?
OMG I wish it never touched acid juice or your teeth - in its original perfect condition it would be worth a LOT! Still a lucky find though. Beautiful pearl.
First glance of the white strand I thought freshwater buttons, but the extraordinary shine quickly made me suspect - any chance they are imitations?
The black strand looks dyed freshwater to me, because of the shapes. They do have beautiful luster, too!
Oh my goodness... I feel sorry for the pearls... :frown:
Many pearls seem to have the underneath layer of nacre exposed where the powdered nacre went away and left holes. If I were you, I might try using the smoothest side of a nail buffer to buff off the white powdering coating and hopefully...
They definitely look like nucleated. Given the size, they might be nucleated baroque freshwater or baroque Akoya pearls. My first intuition was nucleated freshwater (as you have quoted below), yet the luster whispers to me that they are baroque Akoya - but still I am not so sure, as I don't see...
Beautiful colors. I wonder how the picture was taken ‘cause there’s not even the camera’s black reflection in any of the pearls. Would love to see an image if you win the auction.
IMHO it looks like an imitation. But interested in hearing your story how the Queen gifted it to you - did she or Sir Edward Young personally handed it over to your hands or what?
Holy! Thought "AAAAAAAAAAAAAAAAAAAAAAAAAA" was the pearl's grade :shocked: until I saw the "H" :lmao:.
Sounds like a cool pearl. Please remember to share a pic or two once you receive it.
