What to make with them

The diamond-cut faceting makes these a natural for strung necklaces and bracelets where the angles catch movement, and the 5mm size is well-suited to bead weaving patterns like right-angle weave or peyote where a slightly chunkier bicone adds visual weight without overwhelming the structure.
