Photograph of Opal under the microscope- Opal is the birthstone for October and the zodiac sign Libra. Blonde women wore opal necklaces to protect their hair from losing its color. Queen Victoria loved opals and gave them quite often as wedding presents.
An image of a hydrothermal worm taken at 525 times magnification under a scanning electron microscope. I love SEM images! Hydrothermal worms are deep sea creatures, almost as small as bacterium, and are largely found near hydrothermal vents in the ocean.
