This necklace is one of my husband's favorites. I'm sure it's more about the color than the design seeing that green is one of his colors of choice. The silver foil in the green glass beads lends an interesting bit of shimmer to the necklace without being too flashy, and the silver beads ties the whole thing together nicely.
The rectangular white beads provide a bit of a change from the typical round bead, and make a nice correlation with the focal bead at the center since it's shape is more rectangular or oval than circular. Even the smaller green beads, with their irregular sides, meld with the rectangular white beads in an interesting way.
