In creating this choker style necklace I selected lots of carnelian beads including 5 mm beads, a wave bead, four carved rose beads, two double drilled spacers, twist beads and sterling silver findings including 3 mm faceted beads, end cap beads, a lobster clasp and chain for adjustment. The choker can be adjusted from 16 1/2" to 20". The center carnelian wave bead is oval in shape and is 1 3/16" by 1". The carnelian rose beads are 3/4" in diameter. As this is a choker style necklace, it is meant to fit close to the neck. If there is a slack in fit the choker with fall forward so check your neck measurement before you buy!
