Green blue & gold asymmetric beaded necklace, 18" drop, wear single or doubled

Super fun beaded necklace, unbranded but in the style of, say, Trina Turk (whose clothes I wore it with). The pattern is asymmetric with different colored sections in different lengths and materials. The green and royal blue beads are round shiny plastic; there are 2 sizes of gold-ish geometric beads, also plastic (the gold has a worn patina) and then 2 sections of aqua chain that feels like a coated metal. Each bead is individually hooked together. Very good used condition - a couple beads have tiny dings that I only notice when I really look hard. Looks fabulous worn as a single strand (it has an 18" drop as shown in pix) or doubled-up so you can see more of the bead variety. Note that it doesn't have a latch - it's a single strand. And while it's bright, I wore it year round and always got compliments. Questions? Please leave a comment, and thanks!
