I created this unique adjustable necklace and earring set using hexagon shaped Dumortierite beads, a dark lapis pendant and sterling silver findings including Bali Spacer beads, 4 mm round beads, bulk chain, a hook clasp and ear wires. The necklace can be adjusted from 19" to 21 1/2". The earrings are 1 1/8" plus the ear wire. Although much less expensive Dumortierite resembles dark lapis and nicely complete the pendant.. The Dumortierite beads are mostly 5 to 7 mm in length. I added a Bali spacer bead between most of the Dumortierite bead!
