I wanted to make a simple, single-strand layering necklace in soft aqua tones - these turned out to be exactly what I was looking for. The diameter of the beads is smaller than other 4mm beads I have - they're quite petite, and the width ranges from 1-3mm. Gorgeous hues and depth. Excellent for a breezy summertime layering piece. I added 1.5mm lapis lazuli beads as spacers to add length for a necklace that's about 20" altogether.
