Boulder Opal

Boulder Opal

Boulder Opal is a unique variety of Opal that forms naturally within ironstone host rock. Thin seams of precious Opal develop inside the rock, creating striking flashes of colour against the dark brown matrix. The contrast between the vibrant Opal and the earthy ironstone makes each piece visually distinctive. Traditionally, Boulder Opal is associated with creativity, inspiration and personal strength.
