This beautiful piece is made with Boulder Opal and Matrix from the Yowah region in Australia. The focal stone has an amazing pattern with pockets of green, blue and even some flashes of purple throughout! The unique part about this necklace is that both sides have different colors of opal throughout the matrix pattern making this truly a one of a kind. The triangular stone measures 0.80 inches long and 1 inch wide at the widest part not including the sterling silver bail. The pendant is on a sterling silver 16 " long box chain with a sterling silver clasp.
