of the Agate Cameo
The color of the brazilian
Agate is an unsightly grey, so that obviously nobody could imagine the
hidden beauty of a finished Agate Cameo. The striped agate material that
is used for cutting is called „Lagenstein“ e.g. stones with different layers.
Normally this material is being cut out of Agates with even, parallel layers,
so that the result is a stone with a light layer on top of a dark layer.
The possibility of giving
color to the stone depends on porousity, opal and water content of each
layer. Layers which can be colored easily are called „soft“ and layers
that are difficult to dye are called „hard“. Details of the coloring process
are very well hidden secrets of the various companies. This skill of coloring
Agates has been practised in Idar-Oberstein since the beginning of the
19th century (about 1820) in worldwide unparalleled perfection.
