What is Boulder Opal?
Boulder opal is a rock that contains thin seams and patches of opal surrounded by or attached to its natural host rock. The cutter studies this rock and decides how to cut the best possible gem. That gem might be cut to display seams and patches of precious opal as they appear within their natural host rock. Alternatively, the gem might be cut in an orientation that presents a thin seam of precious opal as the face of the gem with its natural host rock as a backing.
Some people also consider "boulder opal" to be an ingenious cutting style that beautifully utilises small seams and patches of precious opal that are too small to cut into gems of solid opal. Boulder opal is also known as "Natural Opal Type 2".
