South American wood?

Recently acquired several of these...looks like someone was going to use as pen blanks.

Anyone know what they are? I'm assuming south American origins...but no idea.

Good luck as it's often tough to ID tropical woods. There are several websites with pictures for you to compare. I brought a tropical unknown home from FL a few years back. It was a chunk left behind in a place I'll leave unnamed ( a sect there planted trees of the world some years ago) but be assured it was a leftover from the removal of a tropical tree that was seemingly unwanted given the powers that be were done cleaning things up as it were. It looks very similar to Black walnut but not it either. Sort of a combo of mesquite and our walnut. I narrowed it down to like 4-5 choices but never for sure. The fact that tropical trees can have multiple names as you change countries or islands where they grow doesn't help with ID'ing.

For names, this might help.

A local woodturner might be able to help you. Like you mentioned, those look like pen blanks.
So many exotics "look alike" that other senses can help - smell can help with ID bigtime, if your familiar enough with it.

The bottom piece in the second picture looks like Kingwood to me because of the purpleish tint. Thumbing through a pen supply catalogue would give you pictures of pieces with similar size and shape that could help.
