Fossilized Pearl

by Joe Johnson
(Nokomis, Florida)

Greetings earthlings! My name is Joe and I'm from, no shirt, no shoes, Nokomis Florida.

I am an avid fossil hunter and often find very large clam shells with blister pearls attached to them. I have also found small fossilized pearls in the loose shell than adorns my driveway. They resemble a nascent pearl in every way except for the outer shell, it has always been hazy and less polished in appearance.

I will look through my extensive fossil collection and try to find the one or two that I may have kept. Unfortunately, uncertainty caused me to leave the majority of them where I found them.

I was always suspicious, but never was able to convince mice elf until I found your site.

Thanks for the affirmation, Kari. And keep up the good work!

Paradise stricken,
Joseph Johnson

P.S. I apologize for the lack of photographic evidence. I'm working on it!

Have it x-rayed?
by: Kari

Hi, That sounds fascinating. Maybe a kind dentist would x-ray it for you? Just an idea so you don't have to ruin it.

Let me know if that works.

I've had dentist friends x-ray pearls that I suspected had a bead inside and were cultured and not natural.

Instead of spending lots of cash on GIA reports a simple dental x-ray did indeed show a bead inside proving the pearl to be cultured.

Cheers and thanks for sharing!

fossil clam/oyster/shelfish of some description
by: Justin

Hi how are you, just looking into fossil clams and oysters and wondering what i should do with it.

I found, about 20 years ago, in the outback of Sth Australia where once upon a time the ocean covered the area, deep underground in a riverbed we were crossing during a pipeline construction, a round clay boulder that drew my curiosity.
After smashing the clay with a mash hammer, my curiosity was rewarded with what i think is a probably a fossilised clam, and have kept it since.

It is in near perfect condition although some of the shell came away with the last bits of clay.

I'm curious to know if there is a pearl inside!! Obviously I don't want to just keep smashing it with a hammer to open it, my question is, is there a way to determine the contents of the inside such as xray, or if i should laser cut it?
If there is nothing inside it well that would be a shame to destroy it aye, but wouldn't it be nice of there was a nice surprise in there!!

Thanks in advance,
Warm regards,

Hi Joe,

A fellow from Texas called me last week and told me about loose fossil pearls he has found. I have not seen any photos yet. I've seen photos of fossil pearls that do still look very much like lustrous pearls, while the one in Vienna has lost all of its lustrous beauty. The nacreous deposits could well be blister pearls and it would be interesting to see what's inside. I have found fossilized oyster shells on the Thames foreshore in London. See: I was told if they shells are flat they were wild and if they were irregular and bumpy, they were raised crammed together.

Hey Kari,
I saw the article and found it quite interesting. I am amazed by the texture these "pearls" possess. I have some coprolite pieces that are smoother and more uniform in shape and color.

The large blister pearls I have found and the small loose pearls somehow managed to retain their identity. By that I mean, they looked like a pearl, a very old, dingy pearl. Of course the BP's were in situ and they still had characteristics consistant with nacre buildup.

I knew next to nothing about pearls before visiting your site, but I am now convinced of what I found.

I went through the smaller items in my collection and was unable to locate the small pea-sized pearls I found in the driveway.

I found the large blister pearls in the shell pits I frequent during the rainy season. The rain is necessary to "uncover" the hidden treasures.

The thing is, the BP's I found were in tact and still attached to the inside of the clam. These are very large clams, mind you. Should I look for them to be loose as well?

Needless to say, the next time I "visit" the pit, I will keep my eyes peeled for BP's. I come across hundreds of such clam shells each month during my fossil hunts.

One more question, we also have rather large fossilized oyster shells here. I have found marble sized nacre deposits where the adductor muscle attached to the shell. Are these possibly blister pearls? Is there a pearl under the initial nacre layers?

Again, thanks for taking the time,

Looking forward to photos
by: Kari

Hello Joe,

Looking forward to some photos. Fossilized pearls are often overlooked or not recognized. Did you happen to see this post about what perhaps is the largest fossilized pearl on record which is displayed in Vienna?

Thanks for posting.
