Turquoise, Apatite-(Caf)
Miniature, 4.2 x 3.1 x 1.9 cm
Cananea, Mun. de Cananea, Sonora, Mexico

A very strange and fine pseudomorph from this find down in Mexico. The crystals are relatively sharp, so far as they go, faithfully showing hexagonal apatite crystal form, even though the two crystals are now completely replaced by carving-grade turquoise.
