Have you ever seen a walnut with three segments? You usually just see walnut halves that come from a two segment shell.
However, three segment walnuts do exist and I have proof.
I was looking through the walnuts that I picked up yesterday and guess what I found? See: Picking up Walnuts
Can you see the three segments of the shell here? The three segments are not equal. You can see that one segment is the regular half shell and the other side is divided.
Here is the other end of the walnut. You can better see the division in this picture.
Of course, I had to open it up and see what it looked like inside.
Here are the three pieces of the shell. They look pretty normal, but you can see that two of them are not round.
You can definitely see here that the nutmeat is a bit different. You have six lobes instead of just the normal four.
I looked to see how common three segment walnuts are, and could only find information that they are rare. I did find a three segment walnut on eBay that was selling for about $15.
You would expect then that I only found one. However, I found two that were three segment in the bag of nuts that I picked up. I also found another walnut that was unevenly divided at about 70/30.
Have you ever found a three segment walnut?

We just found one and turned to the Internet to find out if it is a rarity. Sort of a curious finding.
I just found a 3 segment shell and each segment is a third of the walnut.

We have several English Walnut trees and have some 3 segment shells, the current one being in equal segments. Interesting observation — needs more study.
Just found one!
My sister just found one, so I did some research and found your blog. I guess they are considered “lucky.”
I just found one and stumbled on your post.
I However, have not cracked it open in hopes of selling on eBay starting at $1,000,000😜
i also have the same. Will you purchase it?
I collect unusual walnuts.I have found several seamless ones.They are conical in shape and elongated.They came from the same tree on the same season and I never found more on that tree. Quite unique.Some with one seam only,quite a few with three seams and one with four seams.
Thanks for your post. I was just given some walnuts and one of them was a three sectioned. I thought that if there was such a thing as a three segment walnut, it would be a good way to explain the Trinity; something like the shamrock of St. Patrick. Well they do.
I just found out that they are quite common in Uzbekistan
I have found one too but i ate the inner part and now i only have the outer hard cover of three segment walnut.
