Jewelry-making ideas
Use 3mm and 4mm bicones for delicate bracelet patterns and beadwoven accents, choose 5mm and 6mm beads for medium-sized details, or use 8mm beads for necklace accents and earring drops. Picture a bracelet pairing Tanzanite bicones with neutral glass beads, letting the purple facets catch the light as you move.
Combine sizes for a graduated pattern or repeat one size for a consistent design. Pair Tanzanite with coordinating shades or contrasting colors to suit your project.
These Preciosa beads continue the Czech glass beadmaking tradition, with machine-cut facets defining their bicone profile.
