Boulder Opal

Boulder Opal from Utah is a striking natural gemstone in which opal forms within the cracks and cavities of its host rock, creating beautiful contrasts between colorful opal and earthy stone. Depending on the specimen, the opal may display soft blues, greens, creams, or flashes of iridescent color.

Utah is known for opal-bearing volcanic deposits, where silica-rich fluids gradually filled openings in the surrounding rock and hardened into opal over millions of years. Because the opal remains naturally attached to its matrix, every Boulder Opal specimen has its own unique pattern, color, and character.
