The Halcraft Collection Druzy beads are procured from thousands of agate beads that are carved out of valuable rock with runs and holes filled with tiny natural crystals. We love to coat these beads with iris metallic plating so the facets of each tiny natural crystal catches the light like thousands of tiny mirrors, and that is what these Druzy beads are. They are iris coated in dark blue, silver, gold, pink, amber and green iris to be used in specialty jewelry designs. These real Semi-precious Stone Druzy beads are a beautiful and bright option for any jewelry designer.
