Arizona petrified wood is known for its reds, oranges and blacks; this nugget shows its unusual interplay of color. It measures 1" long by x .5" wide, is attached to a copper backing and includes both a 16" 1 mm sterling snake chain and an 18" 2 mm black silicone cord. Like more than one stone but don't need two sets of cords/necklaces? Purchase them both and $16 will be refunded to you. (Second stone only (without additional cords) is $10.00).
