Bead Crocheted Ivory Pearl, Quartz Druzy, and Sterling Necklace

I bead crocheted the band using 4mm off-white Swarovski crystal beads.  The focal point is the quartz druzy cabochon that I cut from a West Texas geode that my husband collected.  The cabochon is set in textured sterling silver.  The focal point is also the clasp.  The necklace is 17 inches (43cm) long.
