I hand knotted this totally natural aventurine necklace, arranging the individual glowing ombre (shaded) stick beads to display the rhythm and diversity of tones inherent to this lovely stone. The individual sticks measure from 2 cm to a little larger than 1 cm in length. The necklace is adjustable from 16 to 21 inches. The findings, clasp and chain are sterling silver. The knotted cord is a strong, green, bonded nylon for maximum durability and suppleness.
