In 1989 I dug this up while preparing a garden at our new house on Long Island. In 2005 I moved and brought it with me. It has remained in the bird bath since then. After soaking it in a bucket of bleach it went back into the bird bath this morning. Hosing it off caused some white flakes to come off.
Any guesses or factual information?

Looks like some kind of quartz 🤔🤔🤔
It's a beautiful chunk of quartz.
my guess: a piece of petrified calcified tree
Looks like a sample of milky quartz.
Don't take it for granite.
With the banding and the glassy white quartz, it looks like a weathered chunk of gneiss. That is, a metamorphosed granite or pegmatite.

I hope we have solved your dilemma or, at minimum, drastically narrowed your choices.
Seriously, just for a moment, let us all know if you ever are able to determine exactly what rock you got!

If you read the responses so far there seems to be a theme. Still waiting for some more input. What do you think?

I am more sure of almost anything, but what your rock might be. I still
think a Quartz family stone, but do lose faith when I hear of the stone
somewhat shedding. My previous
post was an attempt, albeit a poor
effort, to convey my surprise at how
many people were interested enough
to really delve into the matter and to express so many and such varied thoughts and opinions. I really now am interested in your coming up with an answer for the rest of us. Good luck with that, my friend.

yep
gneiss was commonly used for standing stones in Scotland. The Callanais standing stones are Lewisian Gneiss.

Thanks. I think most agree it is a type of quartz. I'm happy enough with that. I've found pictures of many types of quartz, but no perfect matches.
