The elbaite sample at left is of variety rubellite from Nuristan, Afghanistan. It is about 5x12 cm. It's source is a pegmatite.

This elbaite sample is about 5x7 cm and is from Anjanabonoina, Madagascar.

This extraordinary speciment of elbaite is described as being elbaite with albite and lepidolite. While these two dark green elbaite crystals were growing, conditions changed. The second growth phase gave rise to hundreds of thousands of bristly, hairlike crystals. The overall sample is about 22x24 cm. It's source is Minas Gerais, Brazil

The above sample of elbaite is about 30 cm in overall width and is from Pederneira mine, Minas Gerais, Brazil. It is described as elbaite with lepidolite.

The sample below is described as elbaite with eosphorite. It is about 4x11 cm and is from Santa Rosa mine, Minas Gerais, Brasil. Blue-green elbaite, a member of the tourmaline family, is associated here with brown eosphorite. The grooves that run the length of the crystals are typical of tourmalines.

Elbaite variety, L-R:

1. 30 carats from Madagascar
2. 110.8 carats from Manchuria
