Opal: October's Colorful Birthstone
The birthstone for the month of October is Opal. Opal is a beautiful mineral that displays the phenomenon known as "play of color", which looks like broad flashes of a rainbow of color across the some or all of the gemstone. This phenomenon occurs when rainwater seeps into arid ground (mostly in the deserts of Australia) where dissolved silica crystalize in a series of layers that forms Opal. These layers are oriented in a way that acts like a prism to scatter light so we can see flashes of the spectral colors. Opal has long been a favorite gemstone of people with unique taste, or those who simply can't pick a favorite color. Recent Opal discoveries in the African nations of Ethiopia and Namibia have brought this gemstone back into the limelight. Below are some examples of contemporary Opal jewelry that is very popular today.
