Fossilized Insect In Opal

Writing in a blog post for Entomology Today, Brian Berger explains that he recently purchased an opal originating from the Indonesian island of Java. Dotted with a rainbow of colors—from amber-esque shades of yellow and red to neon green and dark blue—the gemstone is impressive in and of itself. Add in the insect seemingly entombed within, however, and the opal transforms from a precious stone into a significant scientific discovery. Take a look.
