Stone Twenty-Nine is another quartzite from Birdlings Flat. It finished the polishing process on 19 April, being in the same batch of stones as Stone Twenty-Seven.
This is an example of a stone that has not polished perfectly. Along one edge it is rough, with some small holes. If I wanted to smooth those holes away, using the tumbling process, I would also smooth away a lot of the rest of the stone. The stone would shrink in size quite a bit, and we would lose a lot of the patterns we can see in it today.
