There were 60 stones in the 3lb barrel of Gemstone Beach stones that completed the polishing process on 22 December 2021. Stone #19 and Stone #20 were in that barrel, along with today’s stone, Stone #23.
Stone #23 is maybe the most highly polished stone in this batch, which means it is difficult to photograph without reflections interfering more than usual:
The stone is astonishingly complex. It looks like it might be at least partly brecciated, with many small fragments within it, but the surface has polished very smoothly and seems to have taken a depth of polish.
After a tumble of about 10 days in 400 grit, this stone was tumbled for a similar period in 600 grit before spending 17 days in tin oxide tumble polish and 9 days in a burnishing borax tumble.
The stone is 3.5 cms long, 3 cms wide and 0.5 cm thick. I am not sure what kind of stone it is.
