Handmade Sterling Silver periwinkle Tanzanite Quartz beaded necklace to go with a gemstone pendant - or to be worn alone! Perfect layering piece! Beautiful and simple. I use only top quality materials and Sterling Silver clasps (that may vary a bit). State your length when ordering (from 16-18 inches - extra charge for longer - if no length is specified, 16 inch will be sent). This necklace will be finished with Sterling beads and crystals and is made upon order. Gemstone bead size is 3.5mm. I have genuine Tanzanite beads - these look nearly identical - but the quality even looks better!
