Jewelry-making ideas
Use 3mm and 4mm Jet Black bicones to outline beadwoven motifs, 5mm and 6mm beads for bracelets, or 8mm and 12mm beads for necklace details and earring drops. Imagine a black-and-clear glass bracelet catching the light as the faceted beads move.
Pair Jet Black with bright glass colors for contrast or combine sizes for a graduated monochrome design. These Preciosa beads continue the Czech glass beadmaking tradition, with machine-cut facets defining their bicone profile.
