Opals in October

In honor of October’s colorful birthstone, I offer these incredible photographs by Danny J. Sanchez. They perfectly capture the mystery and exceptional nature of this gemstone.  One hardly knows if they are peering into an aquarium or viewing the birth of a star through the Hubble telescope.  Notice the depth of this naturally occurring mineraloid that, depending on the conditions under which it was formed, deffracts light to create what is called a “play of color” within. Enjoy these scrumptious photographs!
