Jewelry-making ideas
Use 3mm and 4mm bicones for delicate beadwoven accents, 5mm and 6mm beads for bracelet details, or 8mm beads for necklace accents and earring drops. Imagine purple facets catching the light in a pair of earrings, with the AB coating adding iridescent highlights.
Mix sizes for a varied pattern or repeat one size for a consistent design. Keep the Style 301 size difference in mind when combining packs in precise beadwork.
These Preciosa beads continue the Czech glass beadmaking tradition, with machine-cut facets defining their bicone profile.
