Thread: 3 Coticules

Here are three Coticules I managed to acquire last week. For the few people that wonder if natural stones can wear out just have a good look at the big one. At one side it's worn out shy of 1mm (rounded up). Here are the sizes:

Big Coticule Combo: 25.5 x 6.3 x 2.3 cm
Natural Coticule Combo: 17.6 x 4 x 2 cm
All Coticule: 18.3 x 4.1-3.6 x 2 cm

The big one feels really smooth but I have no idea what to do with it. The two others I have lapped and tested. The natural combo is the coursest of the three, but really fast and puts all my other stones to shame. The BBW side seems relatively fast as well and smoother than a BBW I already owned. The brownish Coticule is much smoother than the natural but also way slower.
