Virgin Valley Opalized Tree Branch sectionVirgin Valley, Nevada produces some of the finest opal in the world. Ironically it is highly prone to crazing, and for this type of opal, crazing is due to rapid dehydration once the material is exposed to the atmosphere, resulting in the appearance of craze lines, cracks and fissures. Virgin Valley opal is valued most as material for inlay and also for the spectacular specimens of opalized wood it produces such as this branch section bursting with play of color. 3/4" x 1 7/8" |
