High grade Ultramarine Lapis Lazuli high quality with Pyrite

These are high grade large Lapis beads in a hand knotted necklace. This Lapis has Pyrite flecks and brown blue host rock. View pictures.

The color on this necklace is rich and the beads are approximately 10 to 12mm.

Or high quality about ½ an in around.
They've been hand knotted by me using silk cording. I double knotted between each bead to give the beads a little more more space between each other.

This necklace is 21 inches.

Clasp and ring and beads at the end are Sterling silver.
