Opals are formed from centuries upon centuries of seasonal rains that leach microscopic silica particles from sandstone, carrying them deep into underground fissures and cavities. As the deposited materials dry, the microscopic silica spheres become compressed into a closely-packed lattice. As light travels through this microstructure, it creates a dazzling kaleidoscope of flashing rainbow colors, called play-of-color.

• Perfect for wire-wrap jewelry
• Opalescent flashes are extremely aqua/green/purple in person against a milky background

Approx. 1.5 inches long, will vary slightly between opals
