But not as glorious as the ones already shown -

The darker pink beads are about 2 mm and the lighter pinks - 2.5 mm. Stefany is right about the lack of uniformity making the effect much more interesting.

The second necklace has 3-layer chevrons (inner clear-red-white) with stripes on the outer layer. 5-6 mm diameter. The color combo of brown/black on off-white gives a nice neutral result.
