New Pebbles

My collection of wooden pebbles has some new species of wood...

The first pebble is from a very old forsythia bush. Forsythia has a thick pith inside every branch and that's why this pebble has a hole in the middle.
I have always thought that forsythia (called "golden rain" in Slovak) is poisonous, but it is not. The name "golden rain" is also used for laburnum tree which is poisonous and people just mix it up.

The second pebble is from holm oak. It is not oiled, so the variable wood patterns can be seen better.

This is an offcut from almond wood with extra beautiful colors.

The last two pebbles are replacements for other two that I gave away. The upper one is from plum wood and the lower one from zebrawood. It is not sanded/polished because zebrawood with big open pores looks better that way.
