Additional Information
Ochoco Lace is a variety of tube agate. It comes from the Ochoco Mtns. in Oregon. It forms tubular to moss like structures in a translucent agate base. The tubes or moss can be white or green in color. Since it is a white agate in a clear to milky base I like to use a colored backing material, either green or black jade.

The two cabochons shown were cut by the author and I used a thin slab of green jade as backing, making both into doublets.
