Preciosa Crystal Beads - Bicones

Preciosa crystal bicones, made in the Czech Republic: machine-cut crystal beads shaped like two cones joined at their bases. Our titles often call them "Diamond" or "Dia". Sizes include 3, 4, 5 and 6 mm, in Preciosa color names such as Light Siam, Emerald, Indicolite and Tanzanite, plus AB, AB2x and Aurum coatings.

Use them in beadweaving with braided thread like FireLine or WildFire, which is highly resistant to sharp edges, and in stringing and earrings.

Questions & answers

Is a "diamond" bead the same as a bicone?

Yes. In bead names, diamond means the bicone shape: two cones joined at their bases. Our fire polished and Preciosa crystal bicones are often titled "Diamond" or "Dia".

Are fire polished bicones the same as Preciosa crystal bicones?

No. Fire polished bicones are Czech glass beads, machine-cut and then fire-polished to smooth the facets, while Preciosa crystal bicones are a separate line of cut crystal components. Both come in the same shape, so check which one your pattern calls for.

What thread should I use with crystal beads?

Braided thread like FireLine or WildFire is the usual choice for crystals, because it's very strong, barely stretches and is highly resistant to sharp edges. Save nylon thread for softer work like fringe.

What does "crystal" mean in Preciosa crystal beads?

It's the trade term for cut glass. Preciosa crystal components are made in the Czech Republic, and Preciosa's MAXIMA crystal line is certified Lead-Free Brilliance (under 90 ppm lead).

Ages 16+. Not intended for use by children. Contains small parts that can be a choking hazard.
