Tree Agate Necklace is a rare find. This stone is really dendritic agate. Basically dendrite crystals form into tree or branch-like inclusions which create this unusual patterning. Notice the unusual arrangement each bead holds. It is almost reminiscent of a stone called Chinese writing with the patterning in much the same way. Furthermore tree agate is typically on a white background with green streaks running through. However, in this instance it is beige stone with the black/brown markings. Tree agate is a 6.5 to 7 on the Mohs scale, which makes it perfect to be worn as a necklace.
In conclusion, Tree Agate Necklace is 18.5 inches long. Interspersed between the beads, called rice beads, are faceted black onyx beads. The rice beads measure 10 x 7 mm and the faceted onyx beads are 3 mm. A sterling silver toggle clasp finishes off this interesting piece of jewelry. All in all this is a one-of-a-kind piece that needs a good home!
