This Victorian Vulcanite long faceted bead necklace features graduated beads measuring 7mm to 12mm. It is 30.5 inches in length and showcases beads dating to the mid-1800s. Professionally restrung with knots between each bead, this necklace was crafted using Vulcanite, a natural rubber treated with heat and sulfur that makes it more durable. Vulcanite was popular in Victorian black jewelry as an alternative to Whitby jet.
