What is the scale of this rock ?!![edit]

Siim Sepp@
Is this piece of rock, millimeter, centimeter or decimeter in size, or even smaller or larger ? No clue !!! This image can not (or, at least for a geologist's benefit, should not) be used without this information. Thanks for adding a scale if you can ! -- Eric.LEWIN (talk) 20:28, 24 April 2024 (UTC), edited 20:33, 24 April 2024 (UTC).[reply]
