another mystery hone thread

[Piet]

Considering the dimensions and the chamfered edges of the top I would expect Doorsch's stone to be a Special Stone / La Lune. The sparkles are not the only characteristics of a Special Stone though and there are more stones that sparkle. Having sparkles does give it a good chance to be one.

Perhaps these pictures help to check if it's a Special Stone. I've sold the small one but I'm keeping the large one which is unlabeled. They both have a couple tiny pits and swirly lines.
