DOLOMITE variety COBALTOAN
Kakanda, Shaba, Zaire

DESCRIPTION

Dimensions: 4.5 x 2.5 x 0.75 cm

Composition:

Dolomite - CaMg(CO 3) 2

Comments: This is the natural color. The specimen hasn't been dipped in fluorescent pink dye like all those Mexican agate bookends you see along Interstate 10 from California to Louisiana. Minute amounts of cobalt (it can be less than 2%) replaces the calcium cation in the dolomite lattice, allowing for the absorption of the "pink" part of the visible spectrum. The result? A stunning specimen of a mineral that is more often than not just plain white. The numerous crystals on the limestone matrix relfect light in all directions, adding to the aesthetics of the piece. Collected in the 1980's, when the country was still known as Zaire (now Democratic Republic of Congo), the piece comes complete with the label of the late Gilbert Gauthier.
