Opal can be found all over the world, although most Opal is found in Australia. White Cliffs situated in New South Wales, Australia was one of the first viable mining fields and in 1899 it was the largest producer of precious opal anywhere in the world. Dendritic Opal is white in color and has dark markings within the base of the Opal, we loved this stone so much it became the focal point of this design. A scalloped edge solid sterling silver mount houses this magnificent oval stone. A piece sure to be cherished.
