This is a gorgeous Natural Gemstone Kyanite with Lapis Lazuli necklace and 14k Gold Filled extender Chain with lobster clasp. This is adjustable from 17-20” approximately. The large Kyanite beads are raw 14 mm hexagons and the smaller Kyanite beads are 4 mm faceted. The Lapis Lazuli beads are the dark blue accent beads in between the hexagon beads. Both of these gemstones are extremely rare and it is even more rare to see them together in a design.
