Sea opal is a clear dreamy milky white with undertones of pale blue or yellow depending on your light source. I see more yellow in bright sun, and more blue the rest of the time. Sea opal is the name of the color. There's no actual gemstone called sea opal. These are made of glass. They also go by the trade name "opalite". The briolette is a 12x8mm flat faceted teardrop. Beads are meticulously wire-wrapped for beauty and security. Ear wires and wire-wrap are 14 kt. rose gold-filled. 1-1/4" (30mm) long from the top of the lever backs. Gift-ready in either an organza bag (default) or gift box upon request. Packaging styles change with availability.
