What Is Washington Opal Anyway?
Opals are beautiful gems that are known for the way their colors play off of each other, making them look like a fascinating dance of light and color.
The tiny silica spheres that make up these beautiful gems are grouped in a very precise and orderly way. Opals are truly unique because they can bend light, creating a range of colors that change depending on how you look at them.
This effect on light is called “opalescence,” and it’s what makes opals so beautiful and eye-catching. Opals usually grow in the cracks and holes of ancient rocks like shale and sandstone.
Opals can be found all over the world, but Washington state is proud to have its own opal deposits. An opal’s worth may differ according on the location of discovery.
This guide will teach you how to find and identify opals faster, which will help you in your search.
