Formation
Such associations form in granitic pegmatites, where the last, water-rich fraction of a cooling magma crystallises rare elements into large, well-formed crystals.
An Archive combination piece belongs where its contrast can be studied closely, under good light, with room to be seen from several angles.
Significance
Aquamarine is the blue-green variety of beryl, coloured by traces of iron. It commonly grows in pegmatites alongside schorl (black tourmaline) and albite feldspar.
A specimen preserving all three species in association is prized precisely because it records the chemistry of a single pocket, rather than a cleaned single crystal.
Multi-species pegmatite associations are valued for undamaged terminations and clear contrast between the species.
