Jewelry-making ideas
Choose 3mm and 4mm bicones for smaller beadwoven details, 5mm and 6mm beads for repeating bracelet patterns, or 8mm and 10mm beads for larger necklace accents. Picture Sapphire bicones catching the light in a blue bracelet paired with neutral glass spacers.
Combine sizes for graduated designs or repeat one size for a consistent pattern. 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.
Color and shade variations
