fítnau

Fítnau, also known as the Chrysocolla, is a rare type of gemstone obtained from copper deposits. Its name originates from the Saxon and Old English word for a type of blue-green stone, similar to lapis lazuli.

In terms of chemical composition, fítnau is a hydrated copper oxide and phyllosilicate mineral, typically characterizing itself through its vibrant blue and green colors with superb cleavage properties. It holds a significant place in various cultures due to its perceived healing properties.

Gemological studies often describe fítnau as featuring close similarities with the mineral malachite, as both display alternating colors of blue and green due to oxidation. Despite the gem's beautiful appearance and noteworthy occurrences in ancient coinage, it remains challenging to identify and unearth due to its microscopic presence within ores and its consequence as an anomaly within its primary sources.

The first reliable documentation of fítnau sightings dates back to prehistoric times in Northern Europe. Rock collections curated by earlier civilizations emphasize its position as a specifically valuable and associated artifact during resurgence in cabinet collections of Hispano-Arab gemology. Today, collectors actively interests themselves in compiling collection exhibits complete with convertible art certified potentially original fítnau components.
