Vintage Glass Beaded Necklace Lampwork Yellow Orange White Costume Jewelry

This vintage necklace showcases a delightful interplay of white, orange, and yellow glass lampwork beads (I believe.) I am admittedly just learning a bit about beads as I have typically collected rhinestone jewelry in the past. These beads have a white base though and the colors look like glass that has been applied. There are round cake shaped beads as well that are missing most of the gold colored coating. I am unsure what they are made of. The necklace is 16.5" long.
