Stumped....

trying to describe this on google search was pointless and I have yet to find anything similar in all of my reference material.. Anyone have a guess?

You can start with the fact that it has what is called an oolitic texture. Oolitic means egg-like. Maybe you can look up rocks with oolitic textures. Knowing what kinds of rocks it was formed in will help with ID too. See if it bubbles in HCl. That would indicate some kind of carbonate, but many other minerals will also shape up like that.

Almost looks like pieces of ancient seabed with the regular symmetrical shapes. Are you able to get magnified images?

Geology
Check this link, about half way down is a rock that looks similar to what you have.  Stumbled on it while looking into kimberlite.  Hope it unstumps you

Interesting link, thanks. Might be fun to go rockhounding in Antarctica.
