КВАРЦ

What it looks like

The description is in Russian for now — a translation is being prepared. The label is quoted as it reads in the hall, in Russian.

Крупная белая друза кварца на тёмной сланцевой плите на полу у основания столба; синяя табличка.

The name is as on our label in the hall. Where there is no label, we do not assign a name by appearance.
