According to the Rings and Things website, Opalite is a manmade quartz, and is also known as moonstone quartz, opalized quartz, or sea opal. I wonder how one goes about making a new quartz?
Their description reads with words like "ghostly" and "shimmery". I think I'd rather go with shimmery. I'm not too keen on the ghostly look. From the pictures, it looks like a pretty opal blue color with a rainbow effect. I think I'd like to try these sometime. I'll bet it looks really nice with pewter or antique silver findings. Because this is a "cool" color, I'd probably end up accenting it with smaller beads in a warm color like brown or topaz. Have you used opalite yet?
