Celestine in a special form

A celestine in a special form from Madagascar. The unusual geometry of this piece shows an atypical growth anatomy of the Sakoany deposits.

Celestine typically crystallizes in orthorhombic tabular forms or short columns. Most Madagascan pieces follow the classic tabular habit. This 'special form' documents an atypical growth constellation, probably pressure or temperature conditions that deviated from the standard.

Such form variants are valued in the collector's market because they document the range of natural deposit characteristics. They are rarer than the standard tabular habit pieces.

The typical strontium carbonate geochemistry of the Sakoany deposits is also preserved in this variant.
