Kliinikionit

Kliinikionit are small, pigmented stones that are sometimes found in Finland. They are typically made of glauconite, a type of mica that is common in the country's rocks.

Kliinikionit are often mistaken for opals, but they have a few distinct properties that differentiate them. They have a solid, rather than glassy, appearance, and tend to be quite durable. In terms of color, kliinikionit often display a range of shades from blue-green to greenish-yellow.

It is worth noting that the name "kliinikionit" is not widely used outside of Finland, and the stones are more commonly referred to as Finnish glauconite or foyite stones.

The term "kliinikionit" is derived from the Finnish word for "cliniagnosis stone". While it is unclear exactly what the origin of this name is, some theories suggest that it may be related to the stones' association with medical practices or ancient knowledge.

In terms of regional distribution, kliinikionit are commonly found in the southwestern and western regions of Finland, where glauconite is more abundant in the local geology. Some specimens have also been reported from other areas of Europe, though these instances are relatively rare.
